    摘要:

    準(zhǔn)確檢測農(nóng)產(chǎn)品品質(zhì),，可以為采后保存、分期銷售,、預(yù)測產(chǎn)品貨架期以及產(chǎn)品分級提供可靠的依據(jù),。激光多普勒測振技術(shù)基于多普勒效應(yīng)測量從振動物體表面散射回來的光所產(chǎn)生的頻移,，具有靈敏度高,、非接觸性測量、不破壞物體振動等優(yōu)點(diǎn),，可通過測量農(nóng)產(chǎn)品的振動特性實現(xiàn)對農(nóng)產(chǎn)品品質(zhì)的無損檢測,。論述了激光多普勒測振技術(shù)的進(jìn)展、原理及其在農(nóng)產(chǎn)品品質(zhì)無損檢測中的應(yīng)用,。

    Abstract:

    Accurate detection of agro-product quality can provide reliable basis for postharvest preservation, determining when to sell, predicting shelf-life and sorting. Laser Doppler vibrometer (LDV) technology is based on the Doppler-effect sensing the frequency shift of back scattered light from a moving surface, and has the advantages of high sensitivity, non-contact measurement, avoiding mass loading implication and so on. This technology can be used for nondestructive evaluation of agro-product quality by inspecting its vibrational properties. The development and principle of LDV technology, and its applications in nondestructive detection of agro-product quality were introduced.
