Measurement of Temperature Field with Schlieren Shearing Interferometry of Double Frequency Gratings
This paper deals with the natural convection temperature field of unlimited heated Plate with schlieren shearing interferometry of double frequency gratings. The effect of system astigmatism and coma to the interferometry diagram caused by the outaxis irradiation of light source can be reduced to a certain degree by reduction of incidentangle,. increase of radius of reflective mirror, and the adjustment of the position of double frequency grating.
