1. An optical projection system, comprising:
a light source configured to emit modulated light;
a digital mirror device positioned relative to the light source such that the digital mirror device is configured to receive the modulated light emitted from the light source;
wherein the digital mirror device splits the modulated light into doubly modulated light by at least two of angular, spatial, and temporal modulation;
a catadioptric optical sub-system comprising a beam splitter configured to receive the doubly modulated light and convert the doubly modulated light into one or more plane waves.
