Abstract
A system for digitizing light measurements controls the emission of a light source illuminating an illumination region to obtain a constant or near constant signal from a light sensitive device. A light source controllably illuminates an illumination region having a test object using a plurality of light signals. A light sensitive device records the plurality of light signals generally modified by the test object in the illumination region and transmits an output signal corresponding to the modified plurality of light signals. A data processor system receives the output signal and generates a control signal. A light source controller is coupled to the data processor system via the control signal. The light source controller controls the operation of the light source, whereby the emitted light signals are adjustably controllable such that the output signal is constant.
