Abstract
In order to more easily measure the concentration of solution with the Tyndall phenomenon in the outdoor, a portable instrument using image-processing for collecting and processing images of Tyndall phenomenon is proposed. The software and hardware of light measurement module of the portable instrument are described in this paper, including the selection of the incident light and the image sensor. Then the optical path of the captured picture was extracted and the light intensity value was calculated. Through the standard sample, the linear relationship between the light intensity in the Tyndall phenomenon and the concentration was fitted to determine the concentration of the colloidal liquid to be tested. Theoretical analysis and simulation results show that the method of obtaining the concentration of colloidal liquid by using the relationship between the RGB mean of the image and the light intensity of Tyndall can control the error within 10%, which meets the preliminary test requirements.
