The comparative analysis of the characteristics for combined correlators-interferometers is given for the cases of two-beam recording in thin and thick media. It has been noted that the thick medium recording provides the output data bigger accuracy than thin medium recording. Another advance of thick medium recording is the possibility to obtain the set of correlograms describing the object state variations in different moments. This possibility appears due to the multiplexing procedure performance.
Fiber quality estimation by holographic interferometry correlator is presented. The method gives the possibility to test fiber seams and quality homogeneity of the fiber in the laboratory condition. The method is very simple and gives one possibility to provide automatic control of the fiber fabrication.
Influence soluble in liquids gases on changing a refraction coefficient of mixture under its compression was considered. Registration of was realized with holographic interferometer, allowing measure compressibility of liquid and dissolubility of gas under small pressures (near four atm). Distilled water and nitrogen were used because they are mostly explored on necessary characteristics materials. The method of getting of qualitative and quantitative data about the dissolution of gases in liquids is presented.
A correlator-interferometer for the phase objects real time recognition has been developed. The certain conditions under which it may operate successfully, have been examined.
The optimization of the ratios of recording and reconstructing object and reference beams, and also the effect of the dynamic range, resolution and hologram size on the informativity of interferograms are considered, which results in obtaining the higher informativity of real-time holographic interferograms.
A simple and easy to use holographic microscope interferometer (HMI) for biological and material science applications is described. The unit is based on an ordinary microscope accomplished by He-Ne laser, several optical elements, a photothermoplastic (PTP) recorder, and a CCD-camera. Blood and plant cells, as well as internal solid bodies defect images, are demonstrated. Characteristics and application of the unit are discussed.
