摘要:
将低功率激光器(50 mW)应用于PIV测速系统,首次采用微光像增强技术解决光源照度问题. 设计了数字可调同步脉冲光照系统以产生特殊序列脉冲光源. 对垂直进水口旋涡流场的测量表明,本文的方法是可行的.
Abstract:
This article applies low power laser (50 mW) to Particle Image Velocimetry system (PIV). For the first time, it uses the microlight image intensifier to solve the problem of low power illumination. It also designs the digital, adjustable pulse illumination system synchronized with CCD camera to produce the special pulse illumination. Through the measurement of a 2D vortex flow in a perpendicular intake, the feasibility of the method in this article has been tested.
