| 摘 要： | 为了满足监控系统中单镜头可实现全景监控的需求,运用仿生学原理,在原有鱼眼镜头的基础上结合监控系统的需求,运用ZEMAX软件设计了一款视场为180°,相对孔径为1/1.6的鱼眼镜头.该镜头由9片透镜组成,总长度为68.5mm,采用1/3英寸CCD作为图像接收器件.在120lp/mm时,其MTF曲线在轴上大于0.4,在80...

| Abstract: | The bionics principle is used based on the principle of fish-eye lens and monitor control system requirements.A fish-eye lens that FOV is 180° and relative aperture is 1/1.6 is designed with the optical system design software ZEMAX to meet the requirement of the monitor control system on panoramic monitor.The designed system consists nine lenses.The total length is 68.5mm,image receiver is 1/3 inch CCD,the MTF value is more than 0.3 within 0.7 FOV at 80lp/mm,the MTF value of FOV are more than 0.5 within 0 FOV at 120lp/mm.The lens has high distortion because of this lens is a fish-eye lens.Its barrel distortion approximates to 100% within 1.0 FOV. |
