1.An active reflective lens comprising:a lens unit including material that is deformable in response to an electric signal;a support unit configured to support the lens unit;a base unit formed below the support unit;a first electrode formed on the lens unit; anda second electrode formed on the...
An infrared-ray reflective film (100) of the present invention is configured by disposing an infrared reflective layer (20) and a transparent protective layer (30) on a transparent film backing (10) in this order. The infrared reflective layer (20) comprises: a first metal oxide layer (21)...
The light reflected from the wafer based active matrix 46 is reflected by a mirror back surface 48 of the wall 40. The reflected light from the reflective image plane module 30 is directed to a projection lens 50, which lens or lens system can be a fixed or zoom type lens, and projecte...
lithium niobate, or other technology is utilized to present a pattern, the pattern spacing may be modulated to not only change the focal power of the variable focus lens element (166), but also to change the focal power of the overall optical system—for a zoom lens type of functionality....
The invention provides a computer-generated hologram which can be viewed in white at the desired viewing region and a reflective liquid crystal display using the same as a reflector. The computer-generated hologram H is designed to diffuse light having a given reference wavelength λSTD and inciden...
