Abstract

The detection of infrared radiation gathers greater and greater interest with the extension of its practical applications and improvement of the infrared detector performance and their price reduction. In particular it relates to middle infrared region (8 - 12 micrometers ), where powerful CO₂ lasers as well as heterodyne detection of radiation can be utilized. The paper presents the development of direct detection and heterodyne detection systems as well as selected results of investigations of subassemblies and devices. The most interesting results are connected with the application of `multispectral' infrared detectors, reflective a-o modulator integrated with polarizer and Dember effect detectors.
