【摘要】 电子倍增CCD(EMCCD)是用于微光成像的新型CCD,基于EMCCD的遥感器能实现对地夜间可见光观测。本文提出了一种EMCCD相机辐照度自适应系统设计,可让遥感器自动根据景物辐照度的变化更改EMCCD的增益,而不需要人为干预。该设计具有实时性、智能化和灵敏度高等特点。通过EMCCD遥感器样机平台进行了测试,证实了该设计的工程有效性和可行性。更多还原

【Abstract】 Electron multiplying CCD(EMCCD) is a new generation CCD for low light level imaging,remote sensors based on EMCCD can achieve night observation in the visible light spectrum.A design method of irradiance adaptive system in EMCCD camera is presented,which allow camera to adjust EMCCD multiplication gain under the change of scene irradiance without the need for human intervention.The design is of real-time,intelligent and high sensitivity. Moreover,A sensor prototype is manufactured to test,and the effectiveness and feasibility of the design have been confirmed.更多还原
