Abstract

A scanning laser time-delay interferometric detector (TDID) can serve as an excellent optical computer for simple, rapid, high-resolution image reconstruction in a novel multiple- frequency, multiple-transducer acoustic microscope. The new microscope will employ three insonifying transducers to obtain holographic projections from three different directions and using three different frequencies in reconstructing tomograms of microscopic objects. To do this the detection system should detect with equal sensitivity in all directions of propagation of the traveling ultrasonic waves that emerge from the object with the image information. The TDID is capable of accomplishing this task and at the same time providing high resolution, high detected signal strength and a quadrature output for producing the necessary holographic projections.
