Research on Electro-optical Composite Detection Mechanism Based on Microchannel Active Substrate

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.
