abstract

The digital holographic interferometry methods that are used in this work nowadays is widely applied to research of temporal dynamics of objects transformation in different processes [1, 2]. Authors use developed stand and software that are used for detecting and controlling of phase changes of transparent objects with time resolution not less than 100 ms for a long time. Samples of recording polymer material for volume holography «Difphen», solid solution of organic dye phenanthrenequinone (PQ) in polymethylmethacrylate (PMMA), were used as an object of research. Samples were prepared in the shape of plane-parallel disks, 40 mm in diameter and thickness (2÷4) mm [3]. The using radiation with wavelength λ=473 nm is located in the region of absorption of PQ and presents by itself a beam of radiation of solid state DPSS laser which is (2.5÷3.0) mm in diameter and its power is of about 50 mWt. The part of the sample that was exposed by the radiation, absorbing energy, is bleaching and heating up. The bleaching process takes place just in localized area (exposed area), while increase of temperature from exposed area to unexposed areas of the sample is spread by heat transfer. For observation of the process of transfer of heat in the quality of probe radiation we use radiation with wavelength λ = 532 nm in spectral area of light-insensitivity the sample. The probe area was 20x20 mm, which allowed us to evaluate thermal effects in object’s area, located out of reach of laser beam 473nm. © (2014) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
