Energy efficient 3D sensor

摘要

The sensor (1) has a light source (3) i.e. LED, including an illumination source (3.1-3.x) and a reception matrix (9) for receiving a complete image of light reflected from areas of a spatial section. An evaluation device (12) determines distance between the areas and the reception matrix, and a supervisory device (13) recognizes an object. The light source illuminates a partial region of the spatial section, which includes an interspace, where the partial region includes a set of sub-partial regions separated by the interspace.
