在过去的二十年中,航空侦察系统经历了很大的变化。随着可以提供足够覆盖范围和分辨率的晶片式焦平面的问世,许多侦察系统开始用电光传感器来取代摄影胶片。这些电光侦察成像系统大多是利用工作于可见光和近红外谱区的电荷耦合器件来获取目标或场景的 Over the past two decades, the aerial reconnaissance system has undergone great changes. With the advent of wafer-based focal planes that provide adequate coverage and resolution, many reconnaissance systems begin to replace electro-photographic film with electro-optic sensors. Most of these electro-optical reconnaissance imaging systems utilize charge-coupled devices operating in the visible and near infrared regions to acquire targets or scenes
