- W4280631969 abstract "Both spatial and spectral information is important for the images analysis. However, their simultaneous processing is connected with certain difficulties caused basically by the deficiencies of the devices of spectrum analysis of the highdefinition images. These devices provide the limited amount of the selected spectral components as well as low processing rate and reliability due to the presence of the mechanically moving parts. These deficiencies can be eliminated by means of application of acousto-optic tunable filters (AOTF) as selective elements. The functional circuit of the devices providing processing of both kinds of information by means of multispectral image processing using AOTF has been shown and described. The character of AOTF diffraction efficiency decreasing due to the deviation of the selected sub-image wavelength from the value defined by Bragg condition, has also been described. The expression and curve describing the decreasing have been obtained from the states of Kogelnik’s couple waves theory. Also the interconnection between spatial and spectral information amounts which could be provided by the multispectral device based on AOTF, has been established and analyzed." @default.
