Formation of contrasting polychromatic object images based on multi-window acousto-optical filtering

The article presents a technique for acousto-optical multispectral imaging based on choosing the most informative spectral channels and the formation of a multi-window transmission function of an acousto-optical tunable filter. The developed algorithm allows one to select combinations of spectral channels that provide high contrast for a given set of objects and backgrounds with known spectra. The method is tested on the contrast visualization of 20 different object-background pairs with a similar color tone. The results of the experiment demonstrate the effectiveness of the proposed method and algorithm.
