Image acquisition and temperature measurement were synchronized using Labview. R. L. Gordon, J. Opt. The refractive index of the cryogenic liquid contained in the prism was estimated using the angle of the prism and the measured angle of deviation of the beam. Natl. Phys.
The method is self-calibrated and easy to use over the range from cryogenic to room temperature. In this technique, all the optical components are kept at room temperature, while the temperature of the liquid under observation varies between room and cryogenic temperatures. Phys. J. S. Hartman, and ﬂuid mercury. The test method may be suitable for measuring the refractive indices of liquids above 1.5000 and at temperatures both below 20°C and above 30°C; however, the test method precision may not apply.
