Features of image formation and registration of the light-shadow boundary in flow refractometer are considered. A new design of refractometer was developed for the state control of poorly transparent and turbid flowing media containing big insoluble particles. A new algorithm for processing the image recorded on a photodiode array for determining of liquid flow parameters has been developed. A new method for contrast degree determining of the light-shadow border has been proposed taking into account features of registration and processing of optical signals. Experimental results are presented.
