| titleOfInvention | On-line grain size measurement system and method using laser-ultrasound |
| abstract | According to the present invention, ultrasonic waves are generated non-destructively in a steel sheet by using a pulsed laser and the ultrasonic waves propagated inside the steel sheet are measured using a laser interferometer, and then attenuation coefficients of the ultrasonic waves are calculated. The present invention relates to an on-line crystal grain size measuring system and method using a laser-ultrasound measuring particle size.n n n The present invention collects the laser scattered light generated by the frequency shift by the ultrasonic wave reflected from the lower surface of the object and returned to the upper surface by irradiating a laser beam for ultrasonic generation and measurement to the same point of the measurement object and the collection The generated scattered light is reciprocated inside the laser-interferometer to generate interference to detect an ultrasonic signal using the intensity of the transmitted interference light and the reflected interference light caused by the ultrasonic wave, and then the ultrasonic attenuation coefficient for each frequency of the detected ultrasonic signal is calculated. The grain size of the measurement object is calculated.n n n According to the present invention, it is easy to measure the on-line grain size, and it is possible to precisely measure by preventing the loss of ultrasonic energy, and the efficient measurement is possible by reducing the influence of the existing plasma radiation light on the ultrasonic detector for ultrasonic measurement. .n n n n Laser, ultrasound, laser-interferometer, grain size, on-line, scattered light, plasma, |
