Abstract: The present disclosure relates to systems, vehicles, and methods for detecting optical defects in an optical path of a camera system. An example system may include an image sensor configured to provide images of a field of view via an optical path that extends through an optical window. The system also includes at least one phase-detection device and a controller. The controller is configured to execute instructions stored in the memory so as to carry out various operations, including receiving, from the image sensor, first pixel information indicative of an image of the field of view. The operations additionally include receiving, from the at least one phase-detection device, second pixel information indicative of a portion of the field of view. The operations yet further include determining, based on the first pixel information and the second pixel information, at least one optical defect associated with the optical path.

Abstract: Example embodiments relate to temporally modulated light emission and defect detection in light detection and ranging (lidar) devices and cameras. An example embodiment includes a method. The method includes detecting, by a first detector via an optical component, a background signal corresponding to a surrounding environment. The method also includes illuminating, by a first light source, a first portion of the optical component with a first light signal. Additionally, the method includes detecting, by the first detector when one or more defects are present in a body of the first portion of the optical component or on a surface of the first portion of the optical component, the first light signal. Further, the method includes determining, by a computing device, when one or more defects are present in the body of the first portion of the optical component or on the surface of the first portion of the optical component.
