Abstract

OMA-III system is used to detect the change of human blood fluorescence spectrum affected by 632.8nm He-Ne laser. The result shows: 3 peaks emerge in this spectrum at near 670nm, 730nm, and 981nm for different types of blood. Within the limits, fluorescence intensity changes linearly with laser power. The fluorescence intensities at the spots of the three peaks decrease with time lasting, and become stable 8 minutes laser. During laser irradiating, the positions of three peaks shift differently for different types of blood. However, there is competition between the peaks of 670nm and 730nm at the same time.
