Abstract

Temperature distributions in transparent solids have been determined by measurements of changes in the refractive index of the sample using a holographic interferometry technique. The steady-state temperature distributions within two samples, fused silica and polymethyl methacrylate (PMMA), were measured to demonstrate the technique. Various errors in the measured temperature distribution caused by refraction and heat losses from the sample are discussed and estimated.
