面向火星探测,设计并研制了一种基于声光可调谐滤波器（AOTF）原理的成像光谱仪地面原理样机。该样机由前置光机系统和后置电子学系统组成,光学系统采用消色差远心光路结构,工作波段为550～1 000nm,光谱分辨率为0.9～4.0nm。在电子学系统中引入可编程片上系统技术,并设计了新型SpaceWire高速总线接口用于数据传输。样机在实验室定标的基础上,搭载于模拟火星探测器上进行了成像试验。试验结果表明：样机成像质量良好;与ASD光谱仪的一致性对比检验表明,光谱测量准确可靠,两者数据匹配精度超过96%。SpaceWire接口实现了100 Mb/s数据率的稳定传输,满足设计指标25Mb/s的要求。样机的研制为AOTF成像光谱技术在火星遥感探测领域的应用奠定了技术基础。

英文摘要：

For mars exploration, a novel prototype of imaging spectrometer consisting of an optome- chanical subsystem and an electronic subsystem was designed based on an Aeousto-optic Tunable Fil- ter（AOTF）. An achromatic telescopic optical system was used in the spectrometer and its spectral range was between 550 nm and 1 000 nm, while the spectral resolution was 0.9-4 nm. In electronic subsystem, a system-on-a-programmable-chip was introduced and data transmission was implemented by employing a novel bus technology of SpaceWire. On the basis of laboratory calibration, the proto- type was installed in the stimulant mars explorer, and a hyperspectral imaging experiment was per- formed. Experimental results indicate that the prototype of imaging spectrometer can offer good ima- ging quality and the measurement identify between the prototype and an ASD spectrometer is over 96%. Furthermore, the SpaeeWire bus can transport data at a rate of 100 Mbps continuously, which satisfies the technique requirement of 25 Mbps. The development of the prototype provides technical foundation for applications of AOTF imaging spectral technique to mars-based remote sensing in fu- ture.
