摘要

为满足军事以及航天等领域对于复合探测的需求,提出了一种可在极微弱光条件下实现复合探测的探测机制。从微通道板光电倍增理论模型的角度介绍了新型器件的工作原理,并分析了复合波导阳极的透射阳极对真空倍增系统造成的约束条件;通过光学传递函数分析方法研究了复合波导阳极的器件特性;基于验证复合波导阳极的相关参数证明了方案的可行性。在复合阳极得到验证的基础上,为改善复合探测性能又提出了一种复合波导栅极,对分流用隔离膜的选择进行了研究,对电子轨迹进行了建模模拟。在真空炉中进行了该新型器件的验证性实验。结果表明:该器件在一束信号光入射情况下能够提取两路信号;相对于复合阳极,利用光学调制的复合栅极器件分辨力提高了1倍。

Abstract

A detection mechanism that can realize the composite detection under extremely weak light condition is proposed in order to meet the needs of composite detection in military and aerospace fields. The operating principle of a new device is described based on the photomultiplier model of microchannel plate, and the effect of transmission anode of complex waveguide anode on the constraints of vacuum photomultiplier system is analyzed. The device characteristics of the complex waveguide anodes are investigated using the analytical method of modulation transfer function. The feasibility of the scheme was proved by verifying the relevant parameters of composite waveguide anode. Based on the verification of the composite anode, a composite waveguide gate is proposed to improve the performance of composite detection, research the membrane for separating electric current, and simulate the electronic trajectory. The new device was test in a vacuum furnace. The results show that the device can extract two signals from a beam of incident light, and compared with the composite anode, the resolution of the composite gate device with composite gate is doubled.
