Abstract： With the development of economy and the change of consumption concept， consumers pay more attention to the quality of fruit compared to the price of fruit. At present， the quality classification means of fruit picking in our country still rely on manual or simple or rough mechanical screening. This paper introduces the principle and development of electronic nose technology， computer vision technology， infrared spectroscopy technology and electrical characteristics testing technology， and compares the different applications of these technologies in the field of fruit nondestructive testing.

Keywords： fruit; nondestructive testing; computer vision; near infrared spectroscopy

近年来我国水果产量增加，目前国内市场以及国外市场对高品质水果的需求也不断增加，水果无损检测和分级能够提升水果的竞争力，有利于我国水果行业的发展。（剩余4521字）
