Optical module and cleaning device

Abstract

An optical module and a cleaning device are provided. The optical module includes: a light source assembly, a receiving assembly, and a field-of-view folding assembly. The light source assembly is used for transmitting a detection signal to detect a target object. The receiving assembly is used for receiving an echo signal reflected by the target object, and the receiving assembly at least forms a receiving field of view in the vertical direction. The field-of-view folding assembly is configured to fold a portion of the receiving field of view to form a first receiving field of view, and the unfolded receiving field of view forms a second receiving field of view. The direction in which the first receiving field of view receives an echo signal is different from the direction in which the second receiving field of view receives an echo signal.

Dependencies are inferred from the claim text.
