Paper Abstract

Tiny droplets deposited on a copper plate were controlled and measured by a developed control technique and by using a simplified optical apparatus, white light and laser light. The technique employs the proportional control combined with shifting movement by an integrator. The droplets were controlled constant for thirty minutes at the preset level of the intensity of scattered light in a control circuit. The droplets were almost a hemisphere form in initial condensation at room temperature and were few tens micrometers in diameter. The controlled mass of a dew droplet was obtained from the volume of its shape and was of the order of 10-8 g.
