Local temperature of solid surface can be obtained by the intonsity ratio between Stokes Bumnn scattering and anti-Stokcs Banian scattering from samples. It is a real time temperature measurement without touching the object. It needs no calibration, but derives from spectroscopic measurement. It meets the requirements of surface physics and new technology development of VLSI. A steady state measurement using a low power laser has been achieved. The analysis and correction of its errors are given.
