| Abstract: | The real time testing of the 2 D temperature field which is produced by a semi column heat source with a plane boundary is carried out by using the shearing interferometry with the orthogonal double frequency gratings and the semi conductor laser.The curve fitting based on the cylindrical functions is used to analyse the interferogram.As a result,the distribution of the two dimension temperature field in the natural convection is given. |
