: Using a He-Ne laser, a comprehensive analysis of both Goos-Hanchen (GH) and Imbert-Fedorov (IF) reflection shifts of an arbitrary oblique linearly polarized light from a plane metallic surface as a function of temperature is carried out. It is shown that the beam light can contribute both spatial and angular shifts depending on its state of polarity. The investigation indicates that the TM-wave radiation at 89° on gold surface produces the most sensitive GH shift with respect to the temperature and decreases as the metal is heated. The linear change of the spatial GH shift is about 80 pm per Kelvin. The IF deviations, on the other hand, have a monotonic ascending behavior which is about 3pm per Kelvin for the spatial shift. This method may serve as part of an alarm system to detect superheated explosive machinery.
