Оценка параметров интерферограмм, необходимых для определения радиуса кривизны в вершине лежащей капли

Abstract

В связи с развитием предложенного ранее способа определения параметров формы испаряющейся капли рассмотрены методы обработки интерференционной картины, возникающей при наложении плоского волнового поля и сферического поля, сформированного вершиной лежащей капли. Целью этих методов является повышение точности и надежности оценок параметров оптической схемы, ответственных за определение радиуса кривизны капли в ее вершине. Предложен метод обработки картины, оперирующий со всей информацией, представленной на цифровой копии интерферограммы, и показано его преимущество в сравнении с локальными методами, оперирующими только с частью такой информации. n connection with the development of the previously suggested method for the evaporating droplet's shape's parameters's determination we investigated the methods of rocessing the interference pattern that arises when applying the flat field and a spherical wave field, generated by vertex sessile drop. The aim of these methods is to increase the accuracy and reliability of the estimated optical system's parameters responsible for determining the radius of the curvature of the drop in its top. The processing picture method is introduced. It operates with all the information presented on a digital copy of the interferogram, and shows its advantage compared to local methods those operate only with a part of such information.
