摘要：

A novel single-beam interferometric measurement of a thermal bump produced by an intensity modulated and focused laser beam is described. The effects of the ac change in optical reflectivity and the displacement of the surface are determined independently by fitting data to a phenomenological theory. This technique is insensitive to sample vibrations and variations in optical path resulting from thermal fluctuations.
