Abstract: To start from microchannel-plate photoelectric multiple model, constraint conditions for vacuum multiplier system caused by anodized transmission of composite waveguide and position-sensitive anodes were studied deeply, and Mott interpolation method was employed to research the electro-optical properties of new optoelectronic device. Firstly, structure and working principle of composite waveguide anode were introduced, and the correspondence between the transmission anode and position-sensitive anode was given. On this basis, constrained relationship between high-speed signal detection and precise positioning of incident light axis was analyzed, and the corresponding devices design and experimental methods were given. Finally, the verification testing of the new device was conducted in vacuum furnace. Test results show that the new device is feasible both in theory and practice,to search for the adaptive adjustment mechanism of interelectrode tunneling voltage is a trend as inevitable for extending its application field.
