摘要：

An acoustic source formed by pulsed laser irradiation has been used to investigate the piezoelectric and acoustoelectric effects within a cadmium sulphide detector. Analysis of detected waveforms has enabled the two effects to be identified. The resulting transducer combination has application to imaging systems, where phase insensitivity may be required.
