Abstract: (839 Views)
In this paper we describe an experimental method for measurement of glucose solution concentration based on laser light diffraction. It is shown that if laser light is diffracted from the edge of a glass plate immersed in a solution, then visibility of diffraction fringes in the central region of diffraction pattern is varied with solution concentration and this variation is periodic. By choosing glass plates with known refractive index and thickness, the accuracy and extent of measurable concentrations can be changed. The proposed method is simple, inexpensive and accurate.
