METHOD OF DETERMINATION OF PEAK-PHASE STRUCTURE OF SUPERSHORT LIGHT IMPULSES BY MEANS OF SPECTROSCOPIC DEVICE Russian patent published in 2009 - IPC G01J11/00 

FIELD: physics, optics.

SUBSTANCE: invention concerns optics and can be used for measuring of peak-phase structure of supershort light impulses of a femtosecond pulse, both radiated by lasers, and any other nature. Method consists that integrated spatial distributions on time register not less, than in two planes of the spectroscopic device which are on various distances from plane of formation of spectrum. Then spend processing of the gained data, consisting that in the allocations gained out of plane of formation of spectrum, eliminate the greasing arising owing to motion of light stain, having the restricted sizes, in a variance direction on plane of recording during impulse existence. As a result in corresponding plane gain the instantaneous allocation of intensity on which spot spatial peak-phase structure of the gained spatial distribution of signal strength in a plane of formation of a spectrum.

EFFECT: simplification of hardware embodying.
