Patent ID: 8730480

Claim:
A testing unit for testing an optical device, the testing unit comprising: a device holder to hold the optical device; a testing electronics module adjacent the device holder, the testing electronics module including electrical contacts for connection to electrical contacts of the optical device and including electronics to measure a response of the optical device; a transparent cover adjacent the device holder; a wall located on a side of the transparent cover opposite that of the device holder, the wall having a first reflectivity; a movable partition that is slidable in and out of a region, wherein the partition has a reflectivity different from the wall; and a processing unit configured to: generate a control signal to cause the optical device to emit light that is transmitted through the transparent cover toward the wall; analyze a first response of the optical device; generate a control signal to cause the movable partition to be moved between the wall and the transparent cover; generate a control signal to cause the optical device to emit light that is transmitted through the transparent cover toward the movable partition; analyze a second response of the optical device; and determine whether or not the optical device passes a test based at least in part on analyzing the responses of the optical device.
