Two thirds of the light from the camera lens was let through the mirror, while the rest was reflected up to the viewfinder screen. [4] The Pellix pellicle mirror was an ultra-thin (0.02 mm) Mylar film with a vapour deposited semi reflecting layer. Since there was no mirror blackout, the user could see the image at the moment of exposure. [5]
Automated optical inspection (AOI) is an automated visual inspection of printed circuit board (PCB) (or LCD, transistor) manufacture where a camera autonomously scans the device under test for both catastrophic failure (e.g. missing component) and quality defects (e.g. fillet size or shape or component skew). It is commonly used in the ...
Remote Visual Inspection or Remote Digital Video Inspection, also known as RVI or RDVI, is a form of visual inspection which uses visual aids including video technology to allow an inspector to look at objects and materials from a distance because the objects are inaccessible or are in dangerous environments.

Schematic view of a rigid borescope Borescope in use, showing typical view through the device. A borescope (occasionally called a boroscope, though this spelling is nonstandard) is an optical instrument designed to assist visual inspection of narrow, difficult-to-reach cavities, consisting of a rigid or flexible tube with an eyepiece or display on one end, an objective lens or camera on the ...

In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game , a DVD , or the signal from a TV card .
Pipeline video inspection is a form of telepresence used to visually inspect the interiors of pipelines, plumbing systems, and storm drains. A common application is for a plumber to determine the condition of small diameter sewer lines and household connection drain pipes.
In 1953 Buckminster Fuller used Mylar as a skin for a geodesic dome, which he built with students at the University of Oregon. [8] In 1955 Eastman Kodak used Mylar as a support for photographic film and called it "ESTAR Base". [9] The very thin and tough film allowed 6,000-foot (1,800 m) reels to be exposed on long-range U-2 reconnaissance ...
