Abstract

Holo-shear lens made on dichromated gelatin (DCG) is used as a lateral shear interferometer for measurement of temperature and temperature profile of an axi-symmetric gaseous flame. By using a Fourier fringe analysis technique, high-frequency speckle noise can be filtered out and disturbances of a nonspectral component may also be compensated for. The method is simple and easy to implement.
