Abstract: | By means of a double mirror interferometry a two-dimensional temperature distribution measurement in convective thermal boundary
layers is presented. When the cold air flows along a hot plate model, the interferometric fringe inside the boundary layer
will bend. According to the displacement of the fringe and the relation between temperature and index of refraction, a two-dimensional
temperature profile is obtained. All is accomplished by optical device with the help of micro-computer without any contact
with the flow field.
