Filed:

Feb 27, 2018

Appl. No.:

15/906818

Inventors:

- Longmont CO, US
Gregory J. Fetzer - Berthoud CO, US
Richard Vercillo - Tucson AZ, US
Michael Francis Marnon - Washington DC, US
Thomas Laurence Kraus - Springfield VA, US

International Classification:

G01S 17/00
G01S 7/481
G01S 17/08
G01S 17/42

Abstract:

Embodiments herein provide for improved range response in lidar systems. In one embodiment, a lidar system includes a laser, and a detector. First optics direct light from the laser on a beam path along a first optical axis of the first optics. Second optics image the light from the beam path onto a second plane that is substantially normal to the first plane. The second optics have a second optical axis that differs from the first optical axis. The first and the second optical axes lie in a same first plane. A first line in the first plane intersects a second line in the second plane at an acute angle. The first line is perpendicular to the first optical axis. A spatial filter configured in or near the second plane filters the light from the second optics onto the detector.
