Questions of construction of jet-drop optical measuring systems: principle and modes of operation, capabilities and basic characteristics

Abstract

The article is devoted to optical measuring systems using three types of hydraulic streams as optical elements: an unmodulated jet and two parts of a modulated jet in the mode of forced capillary decay: the unbroken part of the jet and the drip stream. A classification of jet-drop optical measuring systems (JDOMS) has been carried out, their schemes for measuring
product displacements and surface irregularities are presented, which implement a hydrojet interference method for measuring linear dimensions of products and the like drop microscope. The questions of light transmission and control of parameters of hydraulic streams are considered.
