FARM CROP OBSERVATION METHOD, FARM CROP OBSERVATION DEVICE AND METHOD FOR PRODUCING FARM CROP

摘要

PROBLEM TO BE SOLVED: To measure the state inside a farm crop non-destructively and contactlessly.;SOLUTION: OCT (Optical Coherence Tomography ) measurement of rice was conducted using supercontinuum light (SC light) with a center wavelength of 1700 nm, a half-value width of 242 nm, and a band of 1400-1950 nm. Fig. 7(a) is an optical microscope photograph indicating the appearance of the rice, and Fig. 7(b) is an OCT image (a cross-section image in a depth direction and a cross-section image at an xz plane in (a)). The gradation of the OCT image is considered to reflect the concentration and degree of crystallization of starch. Thus, the state inside the rice can be observed by the gradation of the OCT image non-destructively and contactlessly.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2018,JPO&INPIT
