Abstract

In order to realize the light and miniaturization of the imaging telescope of the optical communication system, a design method of the inner baffle array of the compact multi-aperture off-axis beam transmission system is developed in this paper. This method mainly deduces the inclination angle of the inclined section of the inner baffle of the multi-aperture off-axis beam transmission system by the method of spatial analytic geometry, and establishes a compact three-aperture inner baffle array in the off-axis beam transmission system by using 3D modeling software. The bidirectional reflection distribution function (BRDF) of inorganic oxidized Al/SiC, oxidized TC4, untreated carbon fiber reinforced plastic (CFRP), and indene steel was tested by the angular determination scatterometer, and the scattering data of CFRP with the highest cost performance was put into the stray light analysis software to simulate the point source transmittance (PST) of the inclined section and the flush section of the baffle tube array. The simulation results show that the proposed method can effectively improve the cross-talk of external stray light between the sub-aperture of the multi-aperture off-axis beam transmission system.
