据Airforce-technology网1月8日报道
美国防高级研究计划局（DARPA）宣布启动一项新计划，以研制轻型袖珍夜视镜技术。
该“增强夜视眼镜”(ENVision)计划旨在设计研制具有跨多个红外光谱带广域视野的轻型夜视镜。
该技术将取代现有夜视技术，采用普通眼镜的单个平镜片，将光学双筒望远镜安装在头盔上。
该袖珍设备将为飞行员和地面部队提供雾、灰尘和其他模糊物等微光条件下的夜视操作及热视觉。
该计划还将探索使用超薄材料从红外光子到可见光光子的直接光子上转换的夜视技术。
DARPA announces project to develop compact night-vision technology
The Defense Advanced Research Projects Agency (DARPA) in the US has announced a new programme that seeks to develop lightweight and compact night-vision goggle (NVG) technology.
The Enhanced Night Vision in eyeglass form (ENVision) programme is aimed to design lightweight NVGs that will offer a wide field of view (FOV) across multiple infrared (IR) spectrum bands.
The technology will enable replacing the existing night-vision technology that involves binocular-like optics mounted on a helmet with a single flat lens in a pair of regular eyeglasses.
The compact set will provide pilots and ground forces with night vision to operate in low light conditions, including fog, dust and other obscurants, as well as with thermal vision.
A Proposers Day for interested participants is set to be held via webinar on 21 January 2021.
DARPA Defense Sciences Office programme manager Rohith Chandrasekar said: “Our warfighters experience significant neck strain from current NVGs caused by the weight of the optics extending 4in-5in in front of their helmets.
“If you’ve never worn NVGs for hours at a time imagine wearing a baseball cap all day with a two-pound weight attached to the front of the bill; that gives you a small sense of the stress experienced.”
Additionally, the ENVision programme will explore the possibility of night vision using direct photon up-conversion from infrared to visible photons using thin materials.
Chandrasekar added: “DARPA investments over the past decade have led to breakthroughs in the areas of planar optics, detection materials, and novel light-matter interactions.
