1. A method to inspect a targets comprising: a. using a generation laser beam to produce ultrasonic displacements on the target; b. using the generation laser beam to produce time varying thermal transients in the target; c. detecting the ultrasonic displacements at the target; d. detecting the thermal transients in the target by thermally imaging the target at predetermined times after steps (a) and (b); and e. analyzing both detected ultrasonic displacements at the target and thermal imagery of the target yields information about the target.
