Measurement of Temperature Field Based on Digital Holography Technology
The tiny change of temperature changes the refractive index of air, and then leads to the phase change of light propogating through the area where the refractive index has changed. We measure the change of temperature field by using Michelson interferometer and digital holography method. Our technique combined with digital photography can be used to measure hydrofield distribution and changing process, for instance, the density distribution and changing process in airflow and water stream.
