Abstract
The present disclosure relates to a method of laser safety verification for a depth map sensor, comprising illuminating, during a first illumination phase, using a laser illumination system, a first cluster of one or more first pixels of a pixel array of the depth map sensor, while not illuminating a second cluster, different from the first cluster, of one or more second pixels of the pixel array of the depth map sensor; and detecting, during the first illumination phase, a level of illumination of the second cluster.
