Abstract

Abstract

In order to ensure the stable tracking accuracy of the photoelectric tracking and aiming system of the mobile ground station in the complex environment in the field, the optical system and optical structure are designed to solve the problem of imaging spot dispersion of the beacon receiving lens under the working temperature width of -20~40℃. A temperature compensation scheme for driving the compensation lens group with a stepping motor is proposed. The change of optical system performance under extreme temperature conditions and the effect of different temperature compensation schemes are analyzed. According to the requirements of photoelectric tracking and aiming system, the opto-mechanical structure is designed and the mechanical and optical properties are analyzed. The analysis results show that the first-order mode of the system is 370 Hz; the compensation lens group moves forward by 0.695 mm to compensate the dispersion of the optical system imaging spot at -20℃, and the central field spot size is reduced from 73 μm to 3.2 μm and the edge field spot size is reduced from 77 μm to 15.7 μm; moving back 0.885 6 mm can compensate for the dispersion of the imaging spot at 40℃, reducing the central field spot size from 94 μm to 3.9 μm, and the edge field spot size from 96 μm to 21.8 μm. The image quality of the optical system is also detected using a ZYGO interferometer. The RMS (root mean square) valueof the wave aberration is 0.061λ (λ=632.8 nm), and the PV (peak-to-valley) value is 0.466λ, which can satisfy the index requirements of the tracking and aiming system.
