Abstract-Temperature profile of an inclined elliptic cylinder is studied experimentally using optical interferometry. Interferograms of the elliptical cylinder with an isothermal surface were recorded by He-Ne laser. The cylinder were placed with its major axis inclined 30° with respect to the horizontal. Temperature profile around the cylinder was quantitatively reconstructed from the locations of fringe center. The influence of the inclination on the temperature profile around the cylinder was discussed. The results reveal that no symmetry can be found from the obtained interferogram. Optical interferometry is successfully developed to measure the temperature profile around an elliptic cylinder.
