Making use of technology developed for optics, transmission diffraction grating spectroscopy is proposed as a method of measuring ultrasound transducer frequencies. Diffraction grating theory is presented and extended to the case of a new test object proposed to measure a B‐scan transducer's peak frequency. A prototype test object was built and its feasibility tested. The experimental results indicate that the test object performed well and has high measurement precision. The question of measurement accuracy was not resolved by the feasibility test. This complex point is discussed in detail. Recent improvements of the test object and the author's ongoing studies of diffraction grating characteristics are presented.
