ABSTRACT:
A microscope for scanning an object with light and acoustic waves and producing both acoustic and optical images thereof. The microscope includes optical and acoustic lenses that focus both the light and acoustic waves on substantially the same point on the object. In one portion of the microscope the acoustic waves and light propagate coextensively through the same medium. The apparatus generates a simultaneous presentation of both acoustic and optical images formed by the microscope.
