一、概述自从出现激光器后,由于它具有相干性好、指向性好和强皮大等特点,在许多科学领域都得到广泛的应用。同样,激光测速也成为航空、动力机械、气象、水利、化工、医疗等部门的强有力的量测手段。使用传统(如毕托管等)的量测工具,已满足不了要求。应用激光 First, an overview Since the emergence of the laser, due to its good coherence, good directivity and strong skin characteristics, in many fields of science are widely used. Similarly, laser speed measurement has also become a powerful measurement of aviation, power machinery, meteorology, water conservancy, chemicals, medical and other departments. The use of traditional (such as Biot tube, etc.) measurement tools, has been unable to meet the requirements. Application of laser
