DEVICE AND METHOD FOR DETECTING AND DETERMINING CHARACTERISTICS OF IMPULSES Russian patent published in 2006 - IPC G01J11/00 

FIELD: optics.

SUBSTANCE: impulse detector with synchronized detection matrix contains collimated light beam lighting a Bragg cell, excited by input signal, containing impulses of varying modulation, aforementioned cell spatially modulating collimated light beam. Binary optical plate multiplies image of Bragg cell on non-transparent plate, containing multiple slits, each one of which has set length. Optical system of lenses forms spatial Fourier light distribution transformation, as a result of which light intensiveness in focal plane of optical system of lenses is proportional to energetic spectral density of light distribution in slits of non-transparent plate. Detector/processor of focal plane, containing detector matrix, responds to intensiveness of light detected by detector matrix, processes analog output signals and transforms them to initial adjustment commands for detecting and determining impulse characteristics in input signal and generates output signals.

EFFECT: realization of algorithm of synchronized detection matrix with usage of hybrid optical-electrical analog and digital processor.
