一种误差解调相干组束激光系统,该系统包括激光束阵列、小口径反射镜阵列、聚焦单元、组束远场探测单元和子光束远场定位单元,所述的激光束阵列包括多个子光束,所述的小口径反射镜阵列包括多个小口径反射镜,所述的聚焦单元包括反射镜和聚焦镜,所述的组束远场探测单元包括分束镜、旋转选光板、聚焦镜和CCD相机,所述的子光束远场定位单元包括反射镜、阵列透镜、聚焦镜和CCD相机。本发明可同时实现相干组束激光系统中每个子光束两维角度误差的精密探测和子光束间前后抖动的精密探测,解决了相干组束激光系统中由于子光束多及误差多而难以探测及控制的难题。 | The invention discloses an error demodulation coherent beam combination laser system. The system comprises a laser beam array, a small diameter reflecting array, a focusing unit, a beam combination far field detecting unit and a sub-beam far field positioning unit, wherein the laser beam array comprises a plurality of sub-beams; the small diameter reflecting array comprises a plurality of small diameter reflecting lenses; the focusing unit comprises a reflecting lens and a focusing lens; the beam combination far field detecting unit comprises a beam splitter, a rotary light selecting plate, a focusing lens and a CCD camera; the sub-beam far field positioning unit comprises a reflecting lens, an array lens, a focusing lens and a CCD camera. The system can realize precision detection of the two-dimensional angle error of each sub-beam in a relevant beam combination laser system and the precision detection of back and forth vibration among sub-beams at the same time, and solves the problem that detection and control are difficult because the quantity of sub-beams and errors are large in the relevant beam combination laser system。
