Abstract: A dual-mode includes a light source configured to project a structured illumination from which visible light can be filtered. The dual-mode imager also includes a detector configured to capture both the structured illumination and visible light from the scene. A temporal or spatial filter is used to selectively block visible light from one or more portions of the detector while passing the structured illumination to the one or more portions of the detector.

Abstract: A three-dimensional imaging system to reduce detected ambient light comprises a wavelength stabilized laser diode to project imaging light onto a scene, an optical bandpass filter, and a camera to receive imaging light reflected from the scene and through the optical bandpass filter, the camera configured to use the received imaging light for generating a depth map of the scene.
