Abstract

PURPOSE:A device is composed of a light transmissible object having at least one curved protion, a light source, a ligh reflecting section and a phttosensitive element, whereby the amount of changes in the refractive index of the object to be tested can be easily taken out as electrical signals when the refractive index changes from time to time.
