The Use of Single Beam Holographic Interferometry in Temperature Measurements in Rectangular Heat Pipe

摘要

Single beam holographic interferometry is a non-contact optical method and as such possesses considerable advantages, e.g. no inertial errors. This contributes to flexibility and enables observation of the transient processes. which would otherwise be hard to observe. Moreover, the measurement technique covers a large portion of the measured field at the same time (with the same photograph), avoiding the need for point-by-point measurements.
