摘要
针对目前国内太阳观测成像仪器稳像系统的需要,提出了一种基于位置敏感探测器(PSD)的高精度太阳敏感器电子学系统的设计,有针对性地提出了提高灵敏度的设计方案和降低系统噪声的具体措施。该系统噪声水平低于4 n A,在工作范围中心区域具备了0.3″的高分辨能力,可以配合偏摆镜结构组成稳像系统,服务于夸父和SPORT计划等具有高分辨率成像需求的太阳成像仪器。
To meet the needs of image stabilization system of domestic solar observatory imaging instrument,a position sensitive detector( PSD)-based electronics system design for high-precision sun sensor is proposed.Concrete measures are put forward to improve the sensitivity and reduce system noise. At presemt,level of the system noise is lower than 4 n A,and has high resolving power of 0. 3″ in center area of working scope,can cooperate with tip-tilt mirror to make up this system image stabilization system,which serve for Kua Fu and SPORT project and other solar imaging instruments which has high resolution imaging demand.
