Abstract
A system and method for real time optical processing of images by simultaneous combining the variable set of images in selected spectral intervals. Spectral images at a plurality of spectral intervals are collected if needed. According to criteria established in a particular application, coefficients for an optimal combination of selected spectral intervals are calculated. Positive and negative images are continuously captured through the optical filter whose transmission spectrum adjusted to positive and negative coefficients of the optimal combination. Negative images are subtracted from positive images and a sequence of resulting optimized images is displayed in real time.
