摘要： A liquid crystal projection device includes a light source for providing light beams; an optical lens module for receiving and projecting the light beams along an incident light path; and a FLC modulator disposed on the incident light path for receiving light beams transmitting along the incident light path, the light beams then being modulated into image light beams by the FLC modulator, wherein the image light beams are reflected by the FLC modulator along a reflection light path, and wherein the incident light path and the reflection light path are situated at an non-zero angle.

摘要： An optical light engine includes a pair of lenticular microlenslet arrays (MLAs) located on each side of a polarization converter. Non-polarized light from a source in the engine is focused by the first MLA onto cells of the polarization converter which converts the light to a common state of polarization to increase efficiency and improve contrast in the system. A half wave retarder is included on the polarization converter to change the polarization of any light that is reflected from downstream optical components to match that of the forward propagating light. The second MLA, which includes a relatively large number of microlenslet elements, collects the light from the polarization converter and homogenizes the light to be highly uniform when received at a downstream imaging panel in the light engine such as a liquid crystal on silicon (LCOS) panel.
