Abstract: A gaming system comprising a time-of-flight 3D camera and related method for illuminating a camera field of view and capturing return image light are disclosed herein. In one example, the time-of-flight 3D camera includes a light source configured to emit source light along an optical axis, and a collimator configured to receive and collimate the source light to create collimated light. A refractive diffuser is operable to be tuned to the camera field of view and configured to receive and diffuse the collimated light to create refracted light having a varying intensity profile. The refractive diffuser is further configured to guide the refracted light to illuminate only a portion of the camera field of view to reduce wasted source light.
