Abstract
An analysis is made of an infrared chopper based on the refraction of light rays by a low frequency (~l-MHz) standing acoustic wave in a block of material such as germanium. Computer programs are described for tracing the rays through the acoustic field and for calculating the contrast ratio at a small aperture detector following the chopper. Experimental results obtained with a germanium device are in good agreement with the theory.
