A method for the measurement of red blood cell velocity in the microcirculation is described. The technique is based on the on-line cross-correlation of the delay between optical signatures derived from photodetectors aligned in direction oflow. A specialised photodiode holder which can be inserted directly in place of an ocular is described. The interdetector delay data is computed automatically from the cross-correlation function by a peak detector designed to provide a voltage proportional to the delay to maximum cross-correlation, regardless of intermediate lower peaks. Application of this system to measurements in the rabbit ear chamber, mesentery and skeletal muscle is described.
本文描述了一种测量微循环中红细胞速度的方法。该技术基于对沿低方向排列的光电探测器所获得的光学信号之间延迟的在线互相关分析。文中介绍了一种可直接插入目镜位置的专用光电二极管固定器。探测器间延迟数据由互相关函数通过一个峰值探测器自动计算得出，该峰值探测器设计为提供与延迟至最大互相关成正比的电压，而不考虑中间较低的峰值。文中还描述了该系统在兔耳室、肠系膜和骨骼肌测量中的应用。
