Abstract
A system for determining the index of refraction of a sample fluid in which light from a collimated light source is directed through a light pervious cell in which sample and reference fluids are held. The light from the collimated light source which is transmitted through the cell is deflected and is then directed through a pair of gratings to establish patterns. When the cell contains a reference fluid therein, first patterns are established, and second patterns are then established by replacing the reference fluid with the sample fluid. A measurement of the change between the first patterns and the second patterns is used for determining the index of refraction of the sample fluid.
