The optical microscope, often referred to as the light microscope, is a type of microscope that commonly uses visible light and a system of lenses to magnify images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although many complex designs aim to improve resolution and sample contrast. Often used in the classroom and at home unlike the electron microscope which is used for closer viewing.
An optical telescope is a telescope that gathers and focuses light, mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct view, or to make a photograph, or to collect data through electronic image sensors.
An overhead projector (OHP), like a film or slide projector, uses light to project an enlarged image on a screen. In the overhead projector, the source of the image is a page-sized sheet of transparent plastic film with the image to be projected either printed or hand-written/drawn. These are placed on the glass surface of the projector, which has a light source below it and a projecting mirror and lens assembly above it. They were widely used in education and business before the advent of computer-based projection..
A zoom lens is a mechanical assembly of lens elements for which the focal length can be varied, as opposed to a fixed focal length (FFL) lens.
In optical engineering, the objective is the optical element that gathers light from the object being observed and focuses the light rays to produce a real image. Objectives can be a single lens or mirror, or combinations of several optical elements. They are used in microscopes, telescopes, cameras, slide projectors, CD players and many other optical instruments. Objectives are also called object lenses, object glasses, or objective glasses.
Macro photography, is extreme close-up photography, usually of very small subjects and living organisms like insects, in which the size of the subject in the photograph is greater than life size . By the original definition, a macro photograph is one in which the size of the subject on the negative or image sensor is life size or greater. However, in some uses it refers to a finished photograph of a subject at greater than life size.
Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's graphical user interface (GUI) to real-time image analysis, but is most often used in reference to interactive 3D computer graphics, typically using a graphics processing unit (GPU). One example of this concept is a video game that rapidly renders changing 3D environments to produce an illusion of motion.
Projectional radiography is a form of radiography and medical imaging that produces two-dimensional images by x-ray radiation. The image acquisition is generally performed by radiographers, and the images are often examined by radiologists. Both the procedure and any resultant images are often simply called "X-ray". Plain radiography generally refers to projectional radiography. Plain radiography can also refer to radiography without a radiocontrast agent or radiography that generates single static images, as contrasted to fluoroscopy, which are technically also projectional.
Magnifier, formerly Microsoft Magnifier, is a screen magnifier app intended for visually impaired people to use when running Microsoft Windows. When it is running, it creates a bar at the top of the screen that greatly magnifies where the mouse is. Magnifier was first included as a sample in the Active Accessibility SDK/RDK for Windows 95 and later made a standard Windows utility starting with Windows 98. Prior to Windows Vista, Magnifier could be used to magnify the screen up to 9 times its normal size. Windows Vista and later allow up to 16× magnification.
A large-format slide projector is a kind of slide projector for large image projection which has a very powerful light source. Therefore, it is necessary to use a large slide format to protect the slide material from overheating during the projection process. Slide formats include 18 × 18 cm or 24 × 24 cm.
An optical comparator or profile projector is a device that applies the principles of optics to the inspection of manufactured parts. In a comparator, the magnified silhouette of a part is projected upon the screen, and the dimensions and geometry of the part are measured against prescribed limits. It is a useful item in a small parts machine shop or production line for the quality control inspection team.
An electronic visual display, informally a screen, is a display device for presentation of images, text, or video transmitted electronically, without producing a permanent record. Electronic visual displays include television sets, computer monitors, and digital signage. By the above definition, an overhead projector could reasonably be considered an electronic visual display since it is a display device for the presentation of an images, plain text, or video transmitted electronically without producing a permanent record. They are also ubiquitous in mobile computing applications like tablet computers, smartphones, and information appliances.
The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly different viewing angles to the left and right eyes. This arrangement produces a three-dimensional visualization of the sample being examined. Stereomicroscopy overlaps macrophotography for recording and examining solid samples with complex surface topography, where a three-dimensional view is needed for analyzing the detail.
Video design or projection design is a creative field of stagecraft. It is concerned with the creation and integration of film, motion graphics and live camera feed into the fields of theatre, opera, dance, fashion shows, concerts and other live events. Video design has only recently gained recognition as a separate creative field. Prior to this, the responsibilities of video design would often be taken on by a scenic designer or lighting designer. A person who practices the art of video design is often known as a Video Designer. However, naming conventions vary around the world, and so practitioners may also be credited as Projection Designer, "Media Designer", Cinematographer or Video Director. As a relatively new field of stagecraft, practitioners create their own definitions, rules and techniques.
The Canon EOS 7D is a cropped sensor digital single-lens reflex camera made by Canon. It was announced on 1 September 2009 with a suggested retail price of US$1,699. Among its features are an 18.0 effective megapixel CMOS sensor, HD video recording, its 8.0 frames per second continuous shooting, new viewfinder which offers 1.0X magnification and 100% coverage, 19-point auto-focus system, movie mode, and built-in Speedlite transmitter.
Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings, small indoor objects or theatrical stages. By using specialized software, a two- or three-dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object. This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative.
In motion picture technology—either film or video—high frame rate (HFR) refers to higher frame rates than typical prior practice.
The Super Bowl XLVI halftime show took place on February 5, 2012 at the Lucas Oil Stadium in Indianapolis, Indiana as part of Super Bowl XLVI. It featured Madonna and guests LMFAO, Nicki Minaj, M.I.A. and CeeLo Green. In 2011, the National Football League (NFL) announced that Madonna would perform at the Super Bowl XLVI show. The singer collaborated with Cirque du Soleil for the show, where her longtime choreographer Jamie King was music director; King, in turn, enlisted the multimedia-show producer Moment Factory. Madonna performed four songs, beginning with "Vogue" in a Roman-Egyptian setting and followed by "Music" with LMFAO. Minaj and M.I.A. joined Madonna for her new single, "Give Me All Your Luvin'", and Madonna finished with Green on "Like a Prayer".
59 Productions is an Olivier and Tony Award-winning design studio and production company with offices in London and New York.
Preclinical or small-animal Single Photon Emission Computed Tomography (SPECT) is a radionuclide based molecular imaging modality for small laboratory animals. Although SPECT is a well-established imaging technique that is already for decades in use for clinical application, the limited resolution of clinical SPECT (~10 mm) stimulated the development of dedicated small animal SPECT systems with sub-mm resolution. Unlike in clinics, preclinical SPECT outperforms preclinical coincidence PET in terms of resolution and, at the same time, allows to perform fast dynamic imaging of animals.
