Summary:

This paper describes a method for the determination of drop size and free water in clouds, based on the interpretation of an artificially created rainbow. Details of the design and operation of an optical instrument employing this method are presented. This instrument is a preliminary design in that the water content and drop size must be kept constant during the interval of the measurement. In designing this instrument, an amplifier which eliminates interference due to shot effect was developed. A mathematical analysis of the rainbow theory is presented in the appendix.
