Abstract
An illumination module includes a light source configured to emit an illumination light beam, a reflective light valve disposed on a path of the illumination light beam and configured to form a plurality of pixels, a lens, and an image sensing module. Each pixel is adapted to be switched between a first state and a second state. The pixels in the first state among the pixels are configured to reflect the illumination light beam into an effective light beam. The pixels in the second state among the pixels are configured to reflect the illumination light beam into a complementary light beam. The lens is disposed on a path of the effective light beam and configured to project the effective light beam to an area to be illuminated. The image sensing module is disposed on a path of a complementary light beam from the reflective light valve and configured to sense the complementary light beam.
