Abstract

Reflection of near-infrared light is measured by commercial equipment. We found that samples in motion and at rest show differences in the intensity of reflection of a laser beam. This may suggest the possibility of its use to detect organ necrosis in vivo. In addition, we find the possibility of the use of this reflection of the near-infrared light for the non-destructive inspection of internal changes in perishables, e.g., their degree of ripeness.
