1. A 3-D imaging system comprising:
- a passively-cooled wavelength stabilized laser diode to project imaging light onto a scene, the wavelength stabilized laser diode including a frequency selective element;
an optical bandpass filter having a transmission range greater than 5 nm full width at half maximum and less than 20 nm full width at half maximum; and
a camera to receive imaging light reflected from the scene and through the optical bandpass filter.

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.
