  • Light engine with lenticular microlenslet arrays
    Patent number: 10088689
    Abstract: 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.
