摘要

折返式全景成像技术作为一种新型的成像技术是光学设计领域近十几年的研究热点，但该技术有一个重大缺陷——在镜头的正前方存在观测盲区。本文设计了一种拥有双观测模式的新型全景成像仪。相比于传统的折返式全景成像仪，该仪器可以同时对前向视场360°×（0°~55°）和环形视场360°×（55°~95°）进行观测。其中，前向视场很好地补充了折返式光学系统的中央观测盲区，并增加了CCD探测器的面积利用率。该成像仪光学系统由前置透镜组、全景环形透镜和中继转像系统三部分组成。所有的透镜表面均为球面，具有易加工、低成本的特点。最后针对这种光学系统设计了对应的机械结构，从而为以后成像仪的加工、装调服务。该成像仪设计为折返式全景成像技术提供了一个新思路。

Abstract

Aiming at the well known drawback of the catadioptric panoramic imaging technology

which has an observation blind area in front of the optical system

a new panoramic imager which has dual observation modes was designed in this paper. Compared with the traditional catadioptric panoramic imager

the instrument proposed could observe the forward 360°×(0°-55°) field of view and ring 360°×(55°-95°) field of view simultaneously. The forward field of view was a good complement to the central observation blind spot in ring field of view

which increased the utilization of CCD detector. The imaging instrument optical system consisted of a front lens group

a panoramic annular lens and a relay imaging system

and all surfaces of the optical system were spherical. The mechanical structure of the new optical system was designed as well. This paper provides a new design method for the catadioptric panoramic imaging technology.
