Abstract
An arrangement of partially reflecting mirror surfaces to extend the dynamic range of area sensor arrays as used in optical measurement systems. An instantaneous optical AGC allows a single area sensor to be used in inspection systems where surface reflectivities and characteristics may vary from diffuse to mirror-like. The partially reflecting mirrors instantaneously superimpose on the area sensor a set of spatially displaced energy related images of the inspection pattern. Electronic readout of the sensor and subsequent data processing allows selection of portions of each image which represent the linear non-blooming operating range of the sensor.
