The company continued on as before into the 1980s, but the original business model began to wane. Robert split the company into Edmund Scientifics and Edmund Optics. [2] Edmund Scientifics marketed to consumers and specialized in science-themed toys, vaguely high-tech household gadgets, and "science gifts."
[2] SLMs are used extensively in holographic data storage setups to encode information into a laser beam similarly to the way a transparency does for an overhead projector. They can also be used as part of a holographic display technology. In the 1980s, large SLMs were placed on overhead projectors to project computer monitor contents to the ...
Holographic optical element (HOE) is an optical component (mirror, lens, directional diffuser, etc.) that produces holographic images using principles of diffraction. HOE is most commonly used in transparent displays, 3D imaging, and certain scanning technologies.
In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light.Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.
Diagram of Lambertian diffuse reflection. The black arrow shows incident radiance, and the red arrows show the reflected radiant intensity in each direction. When viewed from various angles, the reflected radiant intensity and the apparent area of the surface both vary with the cosine of the viewing angle, so the reflected radiance (intensity per unit area) is the same from all viewing angles.
A simple hologram [2] [3]: Section 3.2 can be made by superimposing two plane waves from the same light source on a light recording medium such as a photographic emulsion. The two waves interfere, giving a straight-line fringe pattern whose intensity varies sinusoidally across the medium. The spacing of the fringe pattern is determined by the ...
Light refracts at a dielectric interface, a., establishing a correspondence between rays in the two media, b. Some rays in the higher index medium are left out of the pairing (red) and are trapped by total internal reflection. c. This mechanism can be used to trap light in a waveguide. d.
[2] On 18 June 2012, Canon announced the MR (Mixed Reality) System which simultaneously merges virtual objects with the real world at full scale and in 3D. Unlike the Google Glass, the MR System is aimed for professional use with a price tag for the headset and accompanying system is $125,000, with $25,000 in expected annual maintenance.
