Abstract :
The purpose of this letter is to derive a bound on the number of unique resolvable spots in a photoelastic beam deflection system which is limited by the attenuation of the acoustic wave in the interaction medium. It will also be shown that for a given interaction length, an optimum frequency range exists which yields the maximum number of resolvable spots.
