Abstract
Illumination exposure control systems comprising reflective pixelated spatial light modulators that reflect substantially all of the light impinging on them into at least two different light paths. At least one of the light paths acts as a propagating light path and transmits the light beam out of the lighting system. At least one other light path acts as a non-propagating light path and prevents the light beam from being transmitted out the system. The illumination exposure control systems provide high speed of exposure actuation and precision control of exposure duration and frequency or exposure sequences.
