Abstract

The invention relates to the technical field of laser measurement, and in particular, relates to a device for calibrating a micro anemograph through laser measurement and a use method thereof, and aims to overcome the defect that no special equipment for calibrating the micro anemograph exists at present. A laser Doppler velocimeter irradiates a transparent air channel, tracer particle smoke moving along with wind in the air channel is measured, namely the wind speed in the air channel and serves as a wind speed calibration value, then the wind speed calibration value is compared with the wind speed obtained by an anemograph measuring head after blockage ratio calculation and correction, and thus the accuracy of the anemograph is displayed. The device has the beneficial effects that the laser measurement technology is utilized to solve the problems of low calibration quality and low calibration efficiency of an existing micro anemograph, and the accuracy of the micro anemograph is greatly improved.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a device and method for using laser measurement to calibrate a micro anemometer. Background technique [0002] In many fields such as environmental detection, meteorology, agriculture, biomedicine, industrial equipment, military industry, etc., the flow rate of gas below 2m / s is usually called breeze. Accuracy has also been questioned. [0003] Laser measurement mainly uses the Doppler Effect principle: when the target approaches the radar antenna, the reflected signal frequency will be higher than the transmitter frequency; conversely, when the target moves away from the antenna, the reflected signal frequency will be lower than the transmitted signal frequency. machine frequency. In this way, the relative speed between the target and the radar can be calculated by changing the value of the frequency. [0004] Compared with ordinary microwave radar, laser radar can ...
