Abstract
An acousto-optic device comprises a first light source for producing a light beam, a light-transmitting material capable of transmitting the light beam along an optical path through the light-transmitting material, a light-absorbing material adjacent to the light-transmitting material, and a pulsed light source capable of directing a pulsed light beam at the light absorbing material so as to produce acoustic waves within the light-transmitting material that cross the optical path of the light beam from the first light source.
