不同猪肉组织在太赫兹衰减全反射光谱中的特性差异
Characteristic difference of porcine tissues by terahertz attenuated total reflectance spectroscopy
摘要
Abstract
To investigate the feasibility of testing pork quality by ter-ahertz (THz)spectroscopy nondestructively,refractive indexes and extinction coefficients of fat,muscle and skin of porcine tissue were collected by attenuated total reflection (ATR)mode in the range of 0.2~2.0 THz.The results showed that THz spectra of these tissues were different obviously in 0.2~1.6 THz.Water content was found to be a main factor affecting THz absorption of fresh tissues.The op-tical characteristic difference in THz band of different tissues could be utilized to identify tissue types rapidly and nondestructively.Moreo-ver,it could be predicted that the pork quality could be tested nonde-structively by establishing relationship model of THz spectrum and porcine tissue quality.关键词
