Abstract: A structured light projector outputting light which is adapt to variations in distance between an object under test and the structured light projector can efficiently obtain data as to three dimensions of the object. The structured light projector includes a lens, an infrared laser source, a voice coil motor, a first camera, and a second camera. The infrared laser source can emit infrared light towards the voice coil motor, the first camera is movably housed in the voice coil motor. The voice coil motor can adjust a focal length of the first camera. The first camera is disposed on a transmission path of the infrared light, so that the infrared light enters the to-be-tested object. The second camera is disposed on the second surface, to receive light reflected by the to-be-tested object.
