SPATIAL PHASE RANDOMIZER





The Spatial Phase Randomizer is to remove laser speckles for image with laser illumination. The device employs a spatial phase modulator to modify relative phase across a laser beam and to randomize it rapidly in a time sequence. As a result, laser speckles can be substantially eliminated when laser illumination is observed with naked eye or recorded with a CCD camera.
