Terahertz digital holographic imaging of biological tissues
摘要
Abstract
Terahertz (THz) radiation has low photon energy and high transmissivity and is sensitive to polar materials such as hydrone.Thus,THz digital holographic imaging method has the capacity to acquire biological tissue information rapidly and correctly.Herein,tissue slices of pork and mutton were measured with THz digital holographic imaging system.The experimental images were optimized with method of Fresnel diffraction and the amplitude image of 0.9 THz component was selected for analysis.0.9 THz absorbance image was acquired by calculating tissular absorbance.The results show that all the absorbance of muscle tissue is above 8 cm-1 while that of adipose tissue is less than 4 cm-1.Absorbance score plot is retrieved with Principle Component Analysis(PCA) and the different regions in biological tissue can be distinguished clearly from the results of reestablishment,which show that THz digital holographic imaging technology is able to acquire two-dimensional information of biological tissue with the advantages of short detection time and high efficiency.Thus,it has broad application prospects in the field of biological detection.关键词
