介绍了测定雨雹雨滴大小和速度、测量气象降水水平的光学装置的工作原理。给出了该装置的电子元件和光学元件所需参数的估算。对两种版本的器件结构、狭缝式光膜片和光电二极管阵列进行了测试，并对得到的参数进行了比较。给出了对信号进行处理以计算所用校准系数的方法。给出了该装置的实验室试验结果。
The principle of operation of the optical device for determine the size and velocity of rain and hail drops and measuring the level of meteorological precipitation is described. The estimation of the required parameters of the electronic and optical elements of the device is presented. Two version of the device construction the slit-type diaphragm and arrays of photodiodes were tested and obtained parameters were compared. The methods of the processing signals to calculate calibration coefficients used are shown. The results of the laboratory tests of the device are presented.
