APPARATUS FOR ANALYZING OPTICAL RANGE SIGNAL SPECTRUM Russian patent published in 2004 - IPC

FIELD: acoustic optics.

SUBSTANCE: apparatus includes frequency synthesizer; control unit; registering unit; matching unit; arranged successively according to motion of optical beam forming optical unit and acoustic-optical modulator; connected in series photo detector and integrator. Apparatus includes in addition connected in series and optically coupled optical information inlet unit, optical fiber connected through connection modules with optical information inlet unit and with forming optic unit, focusing lens, aperture, digital-to-analog converter, controlled amplifier, module for connection with registering unit, analog-to-digital converter.

EFFECT: enlarged functional possibilities of apparatus due to analyzing spectrum of optic range signals generated in hard-to-reach zones in aggressive chemical media.
