摘要 | Generally,the observation ranges and detection efficiencies of optical remote sensors can be enhanced using wide-field optical imaging systems. Accordingly,the design and manufacturing of freeform-surface-based optical systems have achieved significant progress recently,making the construction of wide-field,rapid,higher-quality-resolution and -imaging,and obstacle-free off-axis reflection systems feasible. The first part of this paper presents a detailed analysis of the aberration characteristics of an off-axis reflection system. This asymmetric higher level aberration increases dramatically as the field of view(FOV),specifically the meridional FOV,of the system increases. These characteristics place a prominent requirement on image field continuity. The second part of this paper presents a new design approach for two-dimensional(2-D)large FOV optical systems with long focal lengths. First,we built multiple structural forms based on conventional optical systems,leading to a discretized meridional field angle,and with certain specific surfaces of the optical system decomposed into two sub-surfaces. Following this,system optimization was achieved by constraining the system size and improving its structural form. Finally,we designed the off-axis reflective freeform surface optical system. The imaging quality was good within the entire FOV,realizing 2-D large-field imaging of 40°×16°,a focal length of 1 m,and an F-number of 10. The test results prove that the proposed design is good,yielding an optical modulation transfer function of better than 0. 26,particularly in the visible spectrum of 400-750 nm with a characteristic frequency of 50 lp/mm. © 2023 Chinese Academy of Sciences.
