Claim 0:
1. A light detection system comprising:
light sources configured to generate separate beams of light;
a lens array configured to collimate the generated separate beams of light into outgoing light collimated in both a horizontal direction and a vertical direction;
a polarizing beam splitter disposed between the lens array and a mirror assembly, wherein at least a portion of the outgoing light travels through the polarizing beam splitter to the mirror assembly;
the mirror assembly comprising a first scanning mirror configured to move and horizontally sweep the collimated outgoing light across an examined area of interest along the horizontal direction and a second scanning mirror configured to move and vertically sweep the collimated outgoing light across the examined area of interest along the vertical direction, movements sweeping the collimated outgoing light in the horizontal and vertical directions respectively, across a field of regard to reflect off an object;
a detector configured to sense at least part of the reflected light, the at least part of the reflected light being reflected by the polarizing beam splitter to the detector; and
one or more processors configured to determine a distance to the object based upon characteristics of the sensed reflected light.
