摘要

    摘要
  • 摘要: 基于声光可调谐（AOTF）光谱相机的技术指标和性能要求，采用机械正组补偿方式，实现了10可见光波段连续变焦光学系统的设计。详细介绍各组元的光焦度分配和初始结构的计算过程，并用Zemax光学软件进行设计，对设计结果进行了像质评价和像差分析，并对凸轮曲线进行求解。设计和分析结果表明：该系统在0.38 m~0.7 m波段实现了30 mm~300 mm连续变焦，在空间频率50 lp/mm处调制传递函数（MTF）值最大达到0.7。该系统可工作在可见光波段，具有变倍比大、变焦曲线平滑的特点，能够满足光谱相机的成像要求。
    Abstract: Based on performance and application requirements of acousto-optic turnable filter (AOTF) spectral camera, the positive mechanical compensation was introduced to achieve a visible optical system which was 10 continuous zoom configuration with high speed. Details were given to present the process of focal power distribution and computation of initial structure, the simulation was conducted with Zemax to show the results. Then the image quality evaluation was done, the cam curve was solved and the aberration was analyzed. Results show that the system can realize 30 nm~300 mm continuous zoom at 0.38 m~0.7 m, and the maximum modulation transfer function (MTF) is 0.7 at 50 lp/mm . The system is characterized by large zoom ratio and smooth cam curve, which make the system reach the target of AOTF spectral camera.
