摘要： A 3D camera for measuring distances to object points comprising a semiconductor surface having a plurality of light sensitive pixels each comprising a circuit having a photosensor, a switch and an output terminal. The circuit provides a signal on the output terminal only while light is incident on the photosensor and the switch is closed. A fan beam illuminates the object from a position of the fan beam, which position is defined by a scan angle, so that light from the fan beam is reflected by the object to the pixels. A controller controls the fan beam to illuminate the object at a plurality of scan angles of the fan beam, wherein for each scan angle the controller simultaneously closes a plurality of the switches. For a pixel that generates a pulse when the pixel's switch is closed, the controller determines a distance from the pixel to the object by triangulation responsive to the scan angle and the position of the pixel in the semiconductor surface.
