| 摘 要： | 采用ＯＭＡ—ＩＩ微弱信号检测系统研究了人血液荧光光谱在激光照射下的变化情况。结果表明：在６３２．８ｎｍＨｅＮｅ激光诱导下，不同血液在６７０ｎｍ，７３０ｎｍ，９８１ｎｍ附近出现三个荧光峰；荧光强度在一定范围内与照射激光功率呈线性变化关系；随着激光照射时间的增加，三个峰位上的荧光强度下降，８分钟后趋于稳定值；在激光照射过程中，三个峰位出现不同数值的移动，同时在６７０ｎｍ和７３０ｎｍ两个荧光峰之间出现了竞争。

| Abstract: | OMAIII system is used to detect the change of human blood fluorescence spectrum affected by 632.8nm HeNe 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 intensity at the spots of the three peaks decreases with time lasting and becomes stable 8 minutes later.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. |
