Abstract:
An automatic illuminator test system for producing light having high spatial uniformity comprising:a housing having an exit aperture; a reflector oriented to pass light through said exit aperture; a lamp located with respect to said reflector to direct light against said reflector for producing light output in a first direction toward said exit aperture; at least one structure having a plurality of light transmissive apertures mounted adjacent said exit aperture and which are selectably positionable in front of said exit aperture; an array to be tested; an image transfer system in optical alignment with said at least one structure having a plurality of light transmissive apertures for focussing light onto an image plane for casting light onto at least a two dimensional array; and a control system connected to said array to be tested and connected to and for controlling said at least one structure having a plurality of light transmissive apertures to automatically select a pre-specified one of said light transmissive apertures to align with light leaving said exit port and propagating through said image transfer system based upon an electrical signal from said array to be tested.
