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.
Claims23
A method of characterizing a photo-detector comprising:
- focusing a light beam on the photo-detector surface;
- measuring a response of the photo-detector to the focused light beam;
- moving the focused light beam to another position on the photo-detector surface;
- and
- re-measuring the response of the photo-detector to the focused light beam.
2 more elements
A system for characterizing the surface of a photo-detector comprising:
- a light source to provide a light beam;
- an optical conditioner to focus the light beam on the surface of the photo-detector;
- and
- a positioner to move the optical conditioner so that the light beam moves across the surface of the photo-detector.
