Abstract: The most readily available and least expensive device used to expose very small areas on film, as required for experiments in image processing, has been found to be the electroluminescent panel (EP). This device has several characteristics that are highly advantageous for use in replacing a tungsten light source and a shutter. The EP luminance output is a function of both the ac driving voltage and frequency and can be turned on and off very rapidly. The EP is available in different spectral emission ranges, allowing flexibility in its use; also the spectral emission can be shifted by driving the EP for a specific application. The spectral output, with reference to how it is affected by driving voltage and frequency, is discussed and the spectral match between the film and the EP is shown. Photographs are used to show in detail the results of the EP binary light source and how it has been used in image processing.
