Abstract
A method for optical sensing includes providing a mirror comprising a central reflective region surrounded by a peripheral glare-suppressing region. A beam of light from a laser light source is directed to reflect from the central region so as to pass through an output optic along an axis toward a target scene. The light returned from the target scene through the output optic is focused onto an optical sensor, via collection optics having a collection aperture surrounding the mirror.
