1.前言激光多普勒风速计(LDA)广泛用于测量流体速度。其应用范围随着光纤和固态系统的发展而扩大。与气体激光和光电倍增系统相比,固体 LDA 具有尺寸小、价格低、牢固和轻便等优点。使用固态系统最主要的好处在于该
1. Introduction Laser Doppler Anemometer (LDA) is widely used to measure fluid velocity. Its range of applications expands as optical and solid-state systems evolve. Compared with gas laser and photomultiplier system, solid LDA has the advantages of small size, low price, strong and light. The main benefit of using a solid-state system is that
