Measurement oflaser spectroscopic computed tomography of in vivo plant by means of coherent detection imaging method

摘要

Laser spectroscopic CT images at different regions of an intact cactus plant are reported using coherent de- tection imaging system based on the optical heterodyne detection method. The images were obtained at the wavelengths of 714.5 nm and 1319 nm with continuous wave and single frequency Ti:Al_2O_3 and Nd: YAG lasers, respectively. These laser CT images exhibit clear wavelength dependence that can differentiate the plant internal structure.
