摘要
设计了一种激光眩目器光学系统。该光学系统由准直系统及变倍扩束系统构成,可连续调节激光眩目器出射光束发散角。光纤激光器出射激光波长为525nm,数值孔径0.15,发光面为100μm×25μm,经准直镜组准直,再经变倍扩束系统出射,实现100~200m眩目距离,激光静态眩目面积均为1m×0.24m。通过振镜扫描眩目面窄边方向,使上述眩目距离的激光眩目面积达1m×5m,适用于关口、隘口及通道口的激光眩目要求。光学系统出射光束产生的眩目面,激光功率密度波动小,可有效保持眩目效果。光学系统总长度63mm,结构简单,利于工程化,应用前景广阔。
An optical system of laser dazzler is designed.The optical system is composed of a collimating sys-tem and a zoom beam expansion system,which can continuously adjust the divergence angle of the output beam of the laser dazzler.The output laser wavelength of the fiber laser is 525 nm,the numerical aperture is 0.15,and the lu-minous surface is 100μm×25μm.After being collimated by the collimating lens,and then emitted by the zoom beam expansion system,the glare distance of 100-200 m is achieved,and the static glare area of the laser is 1 m×0.24 m.The narrow edge direction of the glare surface is scanned through the galvanometer to make the laser glare area of the above glare distance reach 1 m×5 m,which is applicable to the laser glare requirements of passes and passageways.The dazzling surface produced by the optical system outgoing beam has a small fluctuation in laser power density,which can effectively maintain the dazzling effect.The total length of the optical system is 63 mm,the structure is simple,it is conducive to engineering,and the application prospect is broad.
