摘　　要：利用紫外探测原理实现了一种日盲区紫外信号探测系统前端,系统前置放大电路中采用高输入阻抗、低输入偏流、低噪声的运算放大器,在对紫外信号放大的同时对噪声信号达到有效的抑制。系统选用熔融石英作为透镜材料,采用折射式单透镜光学系统实现对目标紫外辐射信号的接收。利用该紫外探测系统前端在实验室内可以实现对紫外光源的探测,目前探测距离可达13m。Using the theory of ultraviolet detection,a front-end system used in detection of ultraviolet signal is realized. High input impedance, low input bias current and very low noise operational amplifier are used in preamplifier, and noise is restrained efficiently when ultraviolet signal is amplified. Melted-quartz is used as lens material and receiving ultraviolet signal is realized by single refracting lens optical system. In laboratory, the detection to ultraviolet lamp can be achieved using the set,and detection distance can reach 13 m.
