The polymer materials are widely used in replication technologies. Recently different methods such as polymer imprinting, casting, hot embossing, injection molding were successfully used for polymer replication of the different surface structures with nanometer scale elements [1-4]. However, most investigations are connected only with resolution studies and directed at fabrication of sub-micron...

Some problems arising during global reconstruction from time series are illustrated by reconstruction of etalon equations and modeling of real-world radiophysical systems. Efficiency of specialized approaches oriented to modeling of restricted classes of systems is demonstrated and new specific techniques are proposed.

The characteristics of diffraction efficiency and resolution of dichromated gelatin films derived from Agfa 8E75 HD plates by modified preparing and processing methods are presented. Using these films, fabricating of holographic Fabry-Perot etalon has been demonstrated and characteristic fringes of the Fabry-Perot effect have been observed.

A Fabry-Perot etalon placed in the object plane of a coherent optical processing system can be used as a variable bandpass preprocessing filter. Use of this filter leads to improved correlation signals in a matched spatial filter system. Experimental results are shown and compared with results obtained by two other preprocessing methods.

We present a novel concept of a tailored Gires-Tournois etalon structure and show that such a device is useful for the fabrication of a dispersion-slope compensator with an almost arbitrary dispersion profile and also with tunability in the dispersion slope.

Coherent population trapping (CPT) is a common technique used in compact atomic clocks which requires two-phase coherent laser modes with a frequency difference in the GHz range for alkali atoms [1]. To improve the performance vs size trade-off of Cs atomic clocks, we develop a laser source generating two crosspolarized coherent laser fields at 852 nm. It relies on the dual-frequency and dual-p...
