Narrow-band optical filter for a spectral-selective control device of physical and physicochemical processes

Abstract

Subject of the present paper is the application of a multichannel optical spectrometer performing spectral measurements in specified areas of the optical range using a set of narrow-band interference optical filters that are tuned to certain wavelengths. Tasks of monitoring and controlling the physical and physico-chemical processes and the prospects of using non-contact optical spectroscopy for their solution are considered. Recommendations are given both on the choice of materials for infrared and visible filters. A visible range filter based on a combination of zirconium oxide and silicon oxide layers has been developed.

Conditions for effective detection of the boundary between the oil-covered and clean sea surface in the IR range

“…The obtained result can be further improved by using a receiving optical system with an interference coating specially synthesized with a narrow region of high transparency at a wavelength of 10.6 microns. Methods for the synthesis of such effective coatings are given in [5][6].…”
