ACTUATED MIRROR ARRAY PROJECTION SYSTEM

摘要

PURPOSE: An AMA(actuated mirror array) optical system is provided to improve light utilization efficiency by improving uniformity of light modulation. CONSTITUTION: A light generated from a light source(111) is reflected at a planar member(113) comprising a first plane(114), an edge(115). The incident light that passes through a first propagation path(132) is propagated along a second propagation path(134) after reflection. An AMA panel(118) positioned on the second propagation path(134) has many pixel mirrors(118a) within a determined angle range. A projection lens(120) projects light reflected from the each pixel mirror(118a) on a screen(122) along a third propagation path(136). Many first lenses(123a) of a first micro lens array plate(123) correspond to second lenses(124a) of a second micro lens array plate(124) 1:1.
