Abstract
A LIDAR system comprises a spatial light modulator for displaying a diffractive pattern comprising a hologram of a structured light pattern that is projected onto a scene. The structured light pattern comprises an array of light spots and a light source for illuminating the diffractive pattern to form a holographic reconstruction of the light pattern. A detection subsystem comprises light detection elements that detect light from a respective individual field of view (FOV) of the scene and output a respective detected light signal. A first subset of the individual FOVs are illuminated by a light spot of the light pattern and a second subset are not illuminated by the light spot. The system comprises a processor for identifying noise in a first detected light signal, relating to an individual FOV of the first subset, using a second detected light signal, relating to an individual FOV of the second subset.
