   The diagram shows the mirror system and the synchronized engine that displays light from the high speed video projector. Spinning mirror systems are used to build interactive 3D graphics and autostereoscopic visuals visible to multiple simultaneous viewers, since a different view can be perceived by each viewer depending on the angle of vision.

4. Mirror TV - Wikipedia

   en.wikipedia.org/wiki/Mirror_TV

   A mirror TV consists of special semi-transparent mirror glass with an LCD TV behind the mirrored surface. The mirror is carefully polarized to allow an image to transfer through the mirror, such that when the TV is off, the device looks like a mirror. [2] [3] Placement of a mirror TV is important to ensure both good mirror reflection and ...

5. Spin casting (mirrors) - Wikipedia

   en.wikipedia.org/wiki/Spin_casting_(mirrors)

   Spin casting is a technique for constructing large parabolic mirrors by using the curved surface formed by a rotating liquid (e.g. in a rotating furnace). [1] It is distinct from the spin casting or centrifugal rubber mold casting (CRMC) technique used for casting metal or plastics.

Field of View (light blue) In photography, an omnidirectional camera (from "omni", meaning all), also known as 360-degree camera, is a camera having a field of view that covers approximately the entire sphere or at least a full circle in the horizontal plane.

7. Rotating line camera - Wikipedia

   en.wikipedia.org/wiki/Rotating_line_camera

   A rotating line camera is a digital camera that uses a linear CCD array to assemble a digital image as the camera rotates. [1] The CCD array may consist of three sensor lines, one for each RGB color channel. Advanced rotating line cameras may have multiple linear CCD arrays on the focal plate and may capture multiple panoramic images during ...
