拼接式全景头盔红外夜视仪系统设计

摘要

大视场、轻量化、小型化成像系统是目前各类光电探测设备的发展方向，提出了一种采用4路小口径红外镜头拼接实现全景成像的红外夜视仪设计方案，给出了该全景头盔式红外夜视仪的实现原理。系统由红外物镜系统、图像拼接处理器、OLED微显示器、红外目镜系统组成，确定了全景头盔式红外夜视仪的设计参数，并给出了一个视场可达150°的超大视场红外夜视仪成像系统设计实例。%The imaging system with large field of view, lightweight and small size is a developing direction of modern electro-optic detection equipments. A panoramic infrared night vision segmented by the four pathways and small diameter infrared lens is proposed. The implementation principle of the instrument is introduced. The system is consisted of infrared objective lens, image segmented processor, organic light-emitting diode (OLED) micro-dis-play and infrared eye lens. Design parameters of the instrument are confirmed and a design example with 150° su-per-large field of view is presented.
