Abstract

A scanning lidar (10) suitable for use on an automated vehicle includes a laser (16), a beam-steering means (20), and a controller (28). The laser (16) generates a pulsed laser beam (18). The beam-steering means (20) steers the pulsed laser beam (18) in a direction (24) within a field-of-view (22) of the lidar (10). The field-of-view (22) is characterized as rectangular-shaped. The controller (28) is in communication with the laser (16) and the beam-steering means (20). The controller (28) coordinates operation of the laser (16) and the beam-steering means (20) such that the lidar (10) is characterized by an angular-resolution (40). The controller (28) operates the beam-steering means (20) in accordance with a first rectangular spiral pattern characterized by an aspect-ratio that corresponds to the field-of-view (22). The first rectangular spiral pattern causes a scan-segment to be skipped during a present-scan of the field-of-view (22) due to the aspect-ratio. As such, the field-of-view (22) is not scanned entirely at the angular-resolution.
