摘　　要：为了实现激光告警系统的抗干扰性及宽视场,文章提出应用锥形光纤进行光学探头的设计。该方法是采用端面有锥角的光纤并与光电二极管直接耦合连接实现光电转换,通过测量电压值来表示入射光的能量。文章根据激光告警系统设计要求对锥形光纤角度选择及光纤能量接收进行了分析和实验,实验数据表明,该方法可以增大告警系统的探测视场。In order to realize laser alarming systems with high anti-jamming property and wide field of view,this paper proposes a design scheme for the optical probe by applying tapered fibers.It implements the photovoltaic conversion by the direct coupling of a tapered fiber with a photodiode and indicates the energy of the incident light by measuring the voltage value.It analyzes the selection of the angle of the tapered fiber and the received fiber energy and conducts the relevant experiments according to the alarming system design requirements.The experimental data show that this method can amplify the detection field of the alarming system.
