DEVICE AND METHOD FOR RADIAL AND ANGULAR OR ANGLE INCREMENTATION IMAGE ANALYSIS IN CONFORMITY WITH CONTENT OF FORM AND COORDINATION Russian patent published in 2007 - IPC G06K9/58 G02B27/46 

FIELD: spatial light modulator, in particular, spatial light modulator with radially oriented active light modulation sectors for radial and angular light ray analysis, including Fourier transformation optical images, determining of characteristics of search, coordination or identification of image form content.

SUBSTANCE: segmented radial spatial light modulator has active optical area, containing a set of extended radially active optical modulator sectors, positioned on different angular directions relatively to central axis. Aforementioned light modulator is used during separation and localization of parts of optical images of Fourier transformation from images for determining image characteristics by means of form for registration, preservation, extraction, search and comparison to other images for coordination or almost full coordination. Collateral images may be added to images for increasing optical strength in optical image of Fourier transformation without addition of new content of form and for successive comparison to characteristics of form of another image for identification of almost full coordination in addition to coordination.

EFFECT: increased resolution of spatial f of image along each angular direction.
