| dc.description.abstract | The nondestructive internal quality evaluation of argicultural products has been strongly required from the need for individual inspection. In recent, ultrasonic wave has been considered as a solution for this problem. This study is to construct the ultrasonic inspection system for fruits and vegetables on the basis of pre-knowledge that general frequency band(higher than 100kHz) ultrasonic waves do not transmitted well due to sever attenuation. Our system includes ultrasonic pulser & receiver, transducers(50kHz), acoustic horn, pneumatic controller and signal processing units(PC). In order to confirm the performance, several samples(apple, pear, persimmon, kiwi fruit, potato and radish)were tested, and the result showed sufficient possiblity to apply to NDE of fruits and vegetables. | - |
