In some of the more difficult applications of laser Doppler velocimetry such as in combustion research, transonic flow, transverse wind, and others, the optical signals are too small for classical detection methods. This paper summarizes the theory, experimental prototype hardware, and test results for a new type of highspeed photon-correlation signal processor which is being developed for weak laser velocimeter signals and other photon-resolved signals. The new system may also be considered to be a statistical digital frequency discriminator. It uses full multiplication with 10-nsec delay time and has the potential for extension to the measurement of the velocity correlations and spectra.
在激光多普勒测速仪的一些更具挑战性的应用中，比如燃烧研究、跨音速流动、横向风等，光学信号对于传统检测方法来说太小了。本文总结了一种新型高速光子相关信号处理器的理论、实验原型硬件和测试结果，该处理器正在为微弱激光测速信号及其他光子分辨信号而研发。这种新系统也可被视为一种统计数字鉴频器。它采用延迟时间为10纳秒的全乘法运算，并且有扩展用于测量速度相关性和光谱的潜力。
