Abstract
Characterizing the surface responsivity of a photo-detector includes focusing a light beam on the photo-detector surface and measuring a response of the photo-detector. The focused light beam is scanned across the surface of the photo-detector. The response of the photo-detector at each position may be recorded to allow the responsivity of the photo-detector surface to be characterized.
