| abstract | (57) Abstract: Provided is an optical liquid refractive index measuring device which is small, has high resolution, and is not affected by fluctuation of a light source. SOLUTION: The optical liquid refractive index measuring device of the present invention comprises: A transparent crystal optical member 12 is used. Transparent crystal optical member 12 For example, such as lithium niobate single crystal, and a bottom surface 12c that contacts the liquid to be measured first surface of the refractive index n 1, and the entrance surface 12a forming the bottom surface at a predetermined angle, the bottom surface 12c at a predetermined angle A crystal optical member having an exit surface 12b provided on the side opposite to the entrance surface 12a, and having a birefringence having a discontinuous interface with respect to the refractive index at a boundary surface between the bottom surface 12c and the liquid 1 to be measured. . When light from the light source 14 is incident on the incident surface 12a of the transparent crystal optical member 12, Passes through the inside of the transparent crystal optical element 12, reflected by the boundary surface between the bottom surface 12c and the liquid to be measured 1 is separated into the vertically polarized component light l s and horizontal polarization component light l p, exit surface 12b Emitted from The photodetectors 22 and 24 detect these polarizations, and the signal processor 26 processes these signals to calculate the refractive index n 1 of the liquid 1 to be measured. |
