"An experimental investigation was conducted to evaluate the accuracy and sensitivity of a laser holographic interferometer. Interference fringe patterns of a free convection boundary layer on the surface of a vertical test plate were produced. The plate was heated and designed to produce a linear temperature distribution along its surface.
A thermocouple probe was used to map the temperatures in the boundary layer and these values were compared to temperatures obtained from fringe patterns. Data photographs of the holograms were used in the analysis. The number of fringes obtained were compared to predictions of the Gladstone-Dale Law.
High quality fringe patterns were obtained and the results indicate that the thermocouple measuring device was less accurate in general, although there was agreement in the comparative results. The thermocouple readings were unsteady at positions near the plate surface making accurate readings impossible. The holographic technique was demonstrated to be more accurate than the thermocouple device used for the comparison and yielded results which agree with interference theory.
In conclusion, the laser holographic interoferometer is potentially an extremely accurate device and is capable of measuring gas temperatures in complex systems"--Abstract, page ii.
