A night vision device amplifies this light to visible levels . the light , which is made up of photons , is converted into electrical energy and then accelerated through a thin disk 夜视仪将这种光增强到可视的程度，并把这种由光子构成的光转变为电子能量，然后通过一种很薄的磁盘增加电子能量的强度。
Everything from night - vision goggles to new body armour and armoured humvees has to be shuffled around so that deployed units are fully kitted out , leaving those at home with even bigger gaps 每一件装备，从夜视仪到新型身体装甲以及悍马装甲车，都要移来移去以使布防的战斗单位装备完全，而国内的部队空缺更大。
Similarly , through program executive office soldier , we field a variety of items essential to mission success , including thermal weapon sights , night - vision goggles , the multiband inter / intra team radio and interceptor body armor , which includes an enhanced version of small arms protective for increased ballistic protection 同样，通过“士兵计划执行办公室”的努力，我们有各种类型的器材来确保任务取得成功，包括寻热武器观测仪，夜视仪，多波段班组内/外通讯电台和防弹衣，其中防弹衣还包括了一种提高对轻武器防护性能的加强型号来解决越来越多的流弹保护问题。
J - t cooling is one of the main cooling methods for cooling military infrared chips . this kind of cooler has been widely used in the infrared seeking system of air - bome optical radar , nightvision and missile infrared guiding . in this paper , first we gave a brief introduction about cryogenics , research and development of j - t cryocooler 节流制冷器是军用红外领域红外芯片冷却的几种主要方式之一，采用此原理的节流制冷器被广泛地应用在机械光学雷达红外寻的系统，夜视仪及导弹红外制导系统等武器装备中。
( 3 ) the spectral matching factor of nea phothocathodes for reflecting spectrum of objects under night sky radiation has been studied . the spectral matching factors of typical phothocathodes , such as gaas nea photocathode , s _ ( 251 ) and s _ ( 252 ) photocathode , are calculated and compared . the factors give the explanation of high detection performance of the low - light - level night vision equipments ( 3 )研究了nea光电阴极和夜天光照射下景物反射辐射的光谱匹配系数，计算了gaasnea光电阴极的光谱匹配系数，并将之与s _ ( 251 ) 、 s _ ( 252 )光电阴极的计算结果作了比较，揭示了三代微光夜视仪具有优良探测性能的原因。
The article studies the reflection and radiation light spectrum of the object under the night sky light or with the aid of laser , calculates and analyzes the spectrum matching factor of typical optoelectronic cathode to the common objects and the effect on the light contrast and give the detailed mechanical design of the low light night observing instrument on helmet 摘要本文研究了夜天光照射及激光助视下的景物反射辐射光谱特性，计算并分析了典型光电阴极对常见景物反射的光谱匹配系数及其对照度、对比度等参数的影响，并详细对头盔式微光夜视仪进行结构设计。
