  • Radiation detector employing acoustic surface waves
    Patent number: 3983424
    Abstract: A radiation detector utilizing temperature changes particularly suited for detecting small changes of short duration, such as produced by radiation pulses of microjoules of energy and 10 to 100 nanoseconds duration. An acoustic transmission line with transducers on a substrate providing an acoustic surface wave in the substrate, with the phase change in the wave being a measure of the temperature change at the surface of the substrate.
