NONDESTRUCTIVE TESTING SYSTEM FOR FRUIT QUALITY BASED ON DIELECTRIC PROPERTY
Song Jin · Nondestructive Testing · 2003
The actualities of nondestructive inspection of fruit quality by means of dielectric property and the essential idea and parameters of dielectric property were presented briefly. The equivalent model of medium loss, the nondestructive inspection equipment based on dielectric property and the principle of experiment were given. The equipment was used to inspect apples in low frequency and the result showed that in the range of proper frequency, the parameters of apple dielectric property varied with frequency. Therefore the parameters could reflect the quality of apples on the whole.
