    • PURPOSE: A method and a device for measuring a Poisson's ratio is provided to excite ultrasonic waves by using laser lights of low energy as much as the extent that an ablation is not generated, thereby enabling to measure a Poisson's ratio without damage on a surface of an inspection object. CONSTITUTION: A method and a device for measuring a Poisson's ratio are as follows. Pulse oscillation laser lights for generation ultrasonic waves are irradiated on an inspection object, thereby generating ultrasonic waves in the inspection object. Laser lights for detecting the ultrasonic waves which wavelength is different with the pulse oscillation laser lights for generating the ultrasonic waves are irradiated on the inspection object. The laser lights for detecting the ultrasonic waves receiving a Doppler shift with the vibration of the ultrasonic waves generated by irradiating the pulse oscillation laser lights for generating the ultrasonic waves to the inspection object are received so that lights of intensity depending on an amount of the Doppler shift are output. A waveform of the ultrasonic waves generated in the inspection object based on the amount of the Doppler shift is calculated by using the lights of the intensity depending on the amount of the Doppler shift. A frequency analysis of the waveform of the ultrasonic waves is performed so that frequencies of plate ultrasonic waves of a S1 mode generated in the inspection object and resonant frequencies of longitudinal waves are calculated. The Poisson's ratio is calculated from the calculated frequencies of the plate ultrasonic waves of the S1 mode and the resonant frequencies of the longitudinal waves.
