【摘要】 为了得到数码望远镜开发的最优技术方案,对其设计进行了系统分析,找出了图像传感器类型、有效像素数、光敏面尺寸和结构形式等4个关键因素,并由此给出了4个备选技术方案。采用层次分析法(AHP)对备选方案进行了优选决策,通过实例计算,确定出当前最优技术方案,即采用组合式结构和CMOS图像传感器,图像传感器的光敏面尺寸为1/2英寸、有效像素数为1300k。制作出样机,其望远镜视角放大率8倍,视场角7.2°,照相镜头焦距50mm。进行了对比实验,实验结果与理论分析相符。更多还原

【Abstract】 In order to get the best technical scheme for digital binoculars,the designs of digital binoculars should be analyzed systemically.Four key factors such as image sensor,effective pixels,photosensitive dimension and overall structure of the system should be considered.Based on the above four key factors,four optional technical schemes are listed in the paper.Analytic Hierarchy Process(AHP) is proposed to make such decision.The best technical scheme i.e.,to use assembled structure,CMOS image sensor with 1/2inch photosensitive dimension and 1300k effective pixels is chosen by calculation.A prototype binocular with 8x magnifications,field of view 7.2o and focal length 50mm is fabricated.Contrast experiment corresponds to theoretical analysis.更多还原
