【 摘 要 】

In this article we presented a technique for applying the methods of digital holographic interferometry to analysis the processes, occurring in fluid and solid translucent media under the action o heat sources. The experiments were performed at a small-size stand with the use of a CMOS matrix for recording digital holograms and a computer terminal for data processing. Presented results of investigating the free convection process in a plane water layer and the heat transfer process in a solid, as exemplified by the interaction of radiation with a polymeric recording medium for hologram recording. Features of both processes are examined.
