10 November 2003Coherent optical processing of UHF radio-wave electronic pulses via collinear acousto-optical interaction in a crystalline cell
An attempt is made to use the phenomenon of colinear acousto-optical interaction in birefringent single crystals for purposes of a coherent optical processing of UHF radio-wave electronic pulses in anti-radar system. The exact and closed analytical model for describing this phenomenon in uniaxial crystalline materials is developed if both the acoustic attenuation and spreading the acoustic beam are allowed for. The peculiarities of collinear acousto-optical interaction in a cells made of lithium niobate single crystal are considered for traveling continuous-wave regime as well as for an acoustic cavity under action of relatively short acoustic pulse. The feasibility of applying such an effect to perform processing radio-wave electronic pulses is analyzed in the paper presented and the corresponding opto-electronic algorithm is elaborated. The results of preliminary experiment with the key component for similar active anti-radar system are presented.
