Abstract
With the acousto-optic nondestructive testing technique, phase shifts between the incident and the reflected ultrasound are measured at crit ical angles of the investigated material. This letter is focusing theo retically as well as experimentally on the influence of a small surfac e roughness (some micrometers) of a thick material on the phase inform ation.
