Embodiment Construction
[0008] The components of the microchannel photomultiplier tube with composite waveguide anode for space optical communication of the present invention include a window 1, a photocathode 2, a microchannel plate 3, and an anode, such as figure 1 As shown, the microchannel plate 3 has multiple stages, and a voltage in the same direction is applied between the photocathode 2, the microchannel plate 3 of each stage, and the anode, and the photocurrent is output from the anode. The anode is composed of a transmissive anode 4, an anode microchannel plate 5, and a position-sensitive anode 6. The transmissive anode 4 and the position-sensitive anode 6 are respectively located on the front and back of the anode microchannel plate 5, and the electron beam focusing electrode 7 is located in the last stage. Between the microchannel plate 3 and the transmissive anode 4 , the transmissive anode 4 outputs the photoelectric current of the laser communication signal, and the position sensitive a...
