Abstract
Holographic interferometry is one of the accurate methods for measuring physical quantities such as stress, pressure, vibration, and temperature and refractive index changes especially in transparent solid materials. In this study, a digital Mach-Zehnder holographic interferometry setup was used to measure the induced temperature changes by infrared laser irradiation in a polyethylmethacrylate cell. The obtained results from the interferometric method were in good agreement with the results of the measurement by a temperature sensor.
