Hyperspectrometer based on curved prism fabrication for space application

Optical Fabrication, Testing, and Metrology VI, 2018
High resolution and large relative aperture have been urgent demands for the development of spectrometer. A design method of freeform was presented based on offner structure, The design of large relative aperture was realized by multi variables of freeform surface, the energy of system was doubled.

Formation of contrast images of specified objects by acousto-optic hyperspectrometer by selective spectral registration

Optics and Spectroscopy, 2022
The method of selecting the most informative spectral channels when using an acousto-optic hyperspectrometer in the mode of selective spectral registration is presented. The developed technique makes it possible to select spectral channels in which the maximum contrast of objects is observed against a certain background, provided that their ...

A line of aviation hyperspectrometers in the UV, visible, and near-IR ranges

Journal of Optical Technology, 2016
This paper briefly describes a line of hyperspectral sensors fabricated by ZAO Reagent Scientific Manufacturing Center. These devices are comparable to other countries’ products in their main characteristics (spatial and spectral resolution—0.3 m from an altitude of 1 km and 0.2 nm in the blue–green region, respectively—up to 500 spectral channels, and

A New Method for the Improvement of Frequency Resolution of Microwave Hyperspectrometers

Measurement Techniques, 2019
We propose a new original method aimed at the improvement of the frequency resolution of microwave hyperspectrometers in the SHF range for a given duration of single measurement and sensitivity. The method is based on the combined application of the multireceiver concept and the zero-measurement method.
