Projection device comprising a prism system including at least one totally internally reflecting surface at a boundary between two members of different refractive indices within the prism system
Abstract:
A projection device includes one or more deformable mirror arrays (803) arranged to spatially modulate incident light. A totally internally reflecting surface (809) is arranged to direct light to and from the deformable mirror array (803). The device may include one or more dichroic layers (805) arranged such that the light incident on each dichroic layer (805) is substantially normal incidence to the layer.
Abstract(Chinese):

投影装置包括布置成空间调制入射光的一个或多个可变形反射镜阵列（803）。 全内反射表面（809）布置成将光引导到可变形反射镜阵列（803）。 该装置可以包括布置成使得入射到每个二向色层（805）上的光基本上垂直入射到该层的一个或多个二向色层（805）。
