摘要

本文介绍了用波长为635 nm和650 nm的半导体激光二极管形成的数字散斑图相关法测定血浆凝血酶原时间的结果。实验结果表明，所用的波长可以得到可靠的分析结果。两个波长相关系数的变化几乎相同。双源交替开关的使用将提高系统的可靠性并使随机误差最小化。本文提供了相关系数随时间的曲线和使用所提出的实验室设置进行的15个实验的对比图。

Two-Frequency Speckle Analysis of Plasma Clotting Time

The paper presents the results of evaluating the prothrombin time of blood plasma by the method of digital speckle patterns correlation, formed by semiconductor laser diodes with wavelengths of 635 and 650 nm. The experimental results obtained show, that the wavelengths used in the analysis allow getting a reliable result. The change in the correlation coefficient at both wavelengths is almost the same. The use of two sources with alternate switching will increase the reliability of the system and minimize random error. The paper provides curves of the correlation coefficient versus time and a comparative graph of 15 experiments conducted using the proposed laboratory setup.
