摘　　要：航空遥感作为一种多功能综合性探测技术,在资源探索、区域监测和环境探测等多种行业中被广泛使用。遥感器作为整个技术的核心部分,对其探测的精度和性能的稳定性有着严格的要求,所以遥感器的总体装配过程成为了关键步骤,其中,对主次镜一次像面的补偿检验就显得尤为重要。本文运用计算机全息图技术,针对此遥感器的光机系统结构参数设计出符合相应要求的补偿元件,给出设计图,同时对遥感器的主次镜一次像面进行补偿检验,确保了每一个装调过程的质量能满足光学设计要求的技术指标和精度,给出了相应的实验数据。在此基础上,运用精度理论知识对CGH补偿器制作的误差及一次像面补偿检验的系统误差进行了详尽的讨论和分析,并给出了分析结果。Airborne remote sensing as a multifunctional comprehensive probing technique is widely applied in multiple fields,such as resource exploration,regional monitoring and environment detection. The remote sensor as the core part of whole technology has strict requirements for the precision and property stability. Therefore,overall assembly process of remote sensor becomes the key step. Compensation test of intermediate image plane of primary and secondary mirrors is especially important. This paper applies Computer Generated Hologram（CGH） technology to design compensating components which comply with corresponding requirements in allusion to structural parameters of optical-mechanical system of the remote sensor and gives the design drawing. Meanwhile,compensation test of intermediate image plane of primary and secondary mirrors of remote sensor is conducted to make sure the quality of each assembly and adjustment process can meet technical indexes and precision of optical design. Besides,corresponding experimental data are also provided. On this basis,theoretical knowledge of precision is applied to carry out detailed discussions and analyses of errors of CGH compensator and system errors of compensation test of intermediate image plane,and the analysis results are given.
