中文摘要	介绍了宽视场彩色相机工作原理,相机方案及设计结果.发射前实验室检测结果表明,整机静态分辨率达180lp/mm,信噪比为34dB.用户在发射前对宽视场彩色相机的成像效果进行了初步评估,认为宽视场彩色相机能够正常工作,数据格式正确,图像质量优良,能够进行稳定的数据观测,采集与下传.最后介绍了相机在研制过程中采用的一些新技术.
英文摘要	In this paper,the working principle,specifications,scheme and design result of the Wide FOV Color Camera of the YH-1 satellite are introduced.The static spatial resolution of the camera reaches 180 lp/mm and SNR is 34 dB in the laboratory before launching.According to the user'S request,the images are generated by the camera with diferent manner:in the default working，the first and the second images are completed with the auto exposure algorithm,the others are got with the increased or decreased time of exposure from the second；while in the injected-instruction working,the other images are produced with the appointed time of exposure.For the sake of shooting the bright object in the dark background,experiments are carried out in the dark room and outdoor in night to get images of both a globe and the moon.And the images have been evaluated by the user.The result proved that the camera works well,the data format is correct,the exposure algorithm is successful,the quality of the camera is high，and the data can be collected and sent back correctly Finally some m ain technologies applied during the manufacturing process are introduced.
