A clutter filter configuration tool for a safety laser scanner. The clutter filter configuration tool may first operate the safety laser scanner in an environment to learn the environmental clutter level and present the same to a user. Subsequent to this “teach-in” phase, the configuration tool may provide a clutter filter selection process which presents the environmental clutter level to the user and allows the user to select a suitable configuration for a clutter filter. The configuration tool may also provide a clutter filter simulation process wherein the clutter filter chosen by the user is verified and a test is performed using the selected clutter filter. The results may be reported on a visualized graph. The configuration tool may also determine a real area to be monitored utilizing a floor projection area and an orientation of the laser scanner.

A laser radar device includes: a modulator (8) for causing a transmission seed light beam to branch, and giving different offset frequencies to a plurality of the transmission seed light beams having branched, and then modulating the plurality of transmission seed light beams into pulsed light beams and outputting the pulsed light beams, or for modulating the transmission seed light beam into a pulsed light beam, causing the pulsed light beam to branch, and giving the different offset frequencies to a plurality of the pulsed light beams having branched, and then outputting the plurality of pulsed light beams; a band pass filter (14) in which a frequency band including frequencies of signal components included in a plurality of beat signals detected by an optical heterodyne receiver (13) is set as a pass band and a frequency band not including the frequencies of the signal components is set as a cutoff band; and an ADC (15) for sampling the beat signals passing through the band pass filter (14) at a sampling frequency.

A Light Detection and Ranging (LIDAR) system integrated in a vehicle includes a LIDAR transmitter configured to transmit laser beams into a field of view, the field of view having a center of projection, and the LIDAR transmitter including a laser to generate the laser beams transmitted into the field of view. The LIDAR system further includes a LIDAR receiver including at least one photodetector configured to receive a reflected light beam and generate electrical signals based on the reflected light beam. The LIDAR system further includes a controller configured to receive feedback information and modify a center of projection of the field of view in a vertical direction based on the feedback information.

Methods, devices, and systems of a light imaging and ranging system are provided. In particular, the imaging and ranging system includes a LIDAR sensor and a low-profile optics assembly having a reflective element with a continuous and uninterrupted reflective surface surrounding a periphery of a LIDAR sensor in a light path of the LIDAR sensor. The reflective element is positioned at a distance offset from the periphery of the LIDAR sensor and directs light emitted by the LIDAR sensor to a second reflective element that is substantially similar in shape and size as the reflective element. The second reflective element is arranged above and opposite the reflective element directing the light emitted by the LIDAR sensor to a sensing environment outside the imaging and ranging system.

An apparatus, system, and method of focus compensation for a vehicle-mounted, downward looking optical detection system. A first stage compensator addresses high frequency events needing rapid, small displacement compensation. A second stage compensator addresses lower frequency but sometimes larger displacement compensation.
