The technological developments in the design of an adaptive optical scanning acoustic microscope are described. Its two key elements include a multi-channel acoustic wavefront detector to detect the acoustic wavefront aberration and a highly adaptive acoustic source to correct for the effects of aberration. We present experimental images acquired with the instrument that indicate the degree of performance improvement achieved when adaption is used to correct for material aberration.
