An instrument consisting merely of a semiconductor laser in its own housing was used to measure the blood perfusion in tissue. Use is made of the feedback of Doppler-scattered light to the photodiode in the laser housing. A recording perfusion of a finger under occlusion of blood flow in the arm is shown.
一种仅由置于自身外壳内的半导体激光器组成的仪器被用于测量组织中的血液灌注。利用了多普勒散射光反馈到激光外壳内的光电二极管这一原理。图中显示了手臂血流受阻时手指的记录灌注情况。
