摘　　要：为了减少和避免激光和微波辐射眼损伤,设计研制了防激光、防微波、激光探测告警为一体的多功能防护镜。该防护镜由特定功能的光学部件和光电子模块组成,包括多功能复合防护镜片、镜架和激光探测报警系统。进行了多功能防护镜复合技术研究和防护性能测试。结果表明,该防护镜在激光波长532nm,1064nm,790nm,840nm的光密度为4.0～7.28;可见光积分透过率为18.7%;微波衰减大于20dB;报警系统在532nm,1064nm和840nm激光波长能提供自动检测和声光报警,报警器的探测灵敏度为10^(-7)/cm^2;该防护镜可承受1g质量、300m/s～400m/s速率的钢制球形破片的冲击;防护镜总质量小于200g,该防护镜防护波段宽、对激光和微波的衰减倍率高、防护角大、可见波段透光性好、可分体和组合使用、体积小、重量轻、便于佩戴、适用于个人佩戴防护和光电传感器的防护。在现代光学实验和各种激光与微波作业环境,以及反恐和公共安全中是不可缺少的防护器材。In order to reduce and avoid damage form laser and microwave, multifunction protection goggles, incorporating protective systems against laser and microwave and an integrated warning system was developed. The goggles consist of some optical parts and photoelectron modules that perform a specific function, which include muhifunction protective lenses, frames and laser detection-alarm systems. The key compounded technologies of multifunction protection were studied and protective performance of the spectacles was tested. The result shows that the optical density of this goggles is from 4.0 to 7.28 at the laser wavelength of 532nm, 1064nm, 790nm and 840nm; integral transmittance of visible light is 18.7% ; attenuation value of microwave radiation is more than 20dB; the warning system can provides an automatic detecting and sound-light warning at the laser wavelength of 532nm, 1064nm and 840nm; detecting sensitivity of alarm is 10-7j/cm2; this goggles can resist impact against steel-ball splinter whose mass is lg, speed between 300m/s and 400m/s ; gross weight of the goggles is less than 200g. In addition, the spectacles have characteristics of wide range of protection wavelength, higher attenuation rate for laser and microwave, bigger protection angle, higher transmittance for visible light, usage of separated type and combined type, smaller size, light-weight and convenience to wear. They not only can protect an individual operator against laser and microwave radiation, but also can protect photo-electric sensors. They are also necessary protection equipment in modern optical experiment as well as terrorism opposition and public safety.
