Abstract: Devices, systems, and methods are provided for optical device validation. For example, a system may comprise an optical device operable to emit or absorb light, wherein the optical device comprises a lens having an outer surface. The system may comprise a camera positioned in a line of sight of the optical device, wherein the camera is operable to capture one or more images of the optical device. The system may comprise a computer system in communication with to the camera and operable to calculate a validation score for a captured image of the one or more images and to validate the optical device based on a validation state generated using the calculated validation score.
