摘要
文中详细介绍激光干涉式非接触眼压测量的弱光检测工作原理。通过对系统进行理论分析和实验验证,表明该系统对低于30nW的微弱光信号进行可靠检测,从而解决了激光干涉式非接触眼压测量研究中的一个实质性问题。
In this article, the working principle of faint-optical signal detection for the non-contact measurement of IOP based on laser interfer-ometry is introduced in detail. According to the theoretic analysis and experimental results, the system can reliably detect the faint-optical signal of 30nW, which solves an essential problem in the research of non-contact measurement of IOP based on laser interferometry.
