Abstract
A projector is disclosed for use in a 3-D imaging device. The projector includes a light source formed of a vertical-cavity surface-emitting laser, or VCSEL array. The VCSEL array provides a light source for illuminating a capture area. Light from the VCSEL array is reflected off of objects in the capture area and received within a sensing device such as a 3-D camera. The projector may further include a collimating lens array for focusing the light emitted from each VCSEL in the array, as well as a DOE for patterning the light from the collimating lens array to enable the sensing device to generate a 3-D image of the objects in the capture area.
