The maximum blocked laser energy is proportional to the sphere particle diameter, and the elapsed time of the sphere particle is inversely proportional to the sphere particle velocity, so that the sphere particle diameter and velocity can be calculated. Calibration of the device is typically accomplished by simulating the passage of the precipitation particles being measured through the collimated light region of fig. 1.
