Registration of non-stationary processes, namely snapshot hyperspectral imaging that allows to capture data cube I(x,y,λ) in one measurement act, is of interest for imaging spectroscopy.The purpose of the work is increasing of spectral resolution of

The increase of angular dispersion and slit resolution limit of grating spectrometers by means of variation of grating parameters is limited by its period and allowable order of diffraction. The special solutions (echelle, holographic, immersion grat

The optical design of the apparatus for generation of programmable-spectrum light is proposed. Both wide-band (hundreds of nanometer) and narrow-band (units of nanometer) spectral patterns may be generated by means of the proposed device. The spectra

We have developed a basic approach and a design for snapshot recording of multispectral information, based on a dispersive polychromator with mirror objectives. By means of numerical modeling, we have shown that the halfwidth of the blur spots for 11

We propose a method for retrieval of an optical line spectrum limited to a narrow spectral range using a short interferogram, based on the use of a multi-stage genetic algorithm. We have run simulations for the example of spectra with lines having wa

An axially symmetric optical system for an imaging monochromator with dispersion subtraction for multiple multispectral scans is proposed and simulated numerically. This system provides minimal angles of incidence for beams on spherical objectives so
