这种夜视仪可随时附加于头盔上,不用时可很方便地拆下;如飞行中暂时不用,亦可将其向上转动到不阻挡正常视线的位置.其原理与一般的夜视仪相同,在外界有微光的情况下用光电景象倍增管将景象亮度增强到1万—2.5万倍,在荧光屏上显示出较清晰的景象.该夜视仪的结构如下图所示,其外形象双筒望远镜,每个简均含:物镜组件、景象倍增管组件与目镜组件.两个筒部固定在横向移动组件上.景象倍增管组件是一个内场可更换的组件(SRU).其中含景象倍增管与集成电源.两者被精确地装在醛缩醇的壳体中以保证入射面与物镜景象平面在无限远处相重合物镜组件也是内场可更换的,它有七个
This night vision device can be attached to the helmet at any time, when not available can be easily removed; such as temporarily not in flight, it can be turned up to the position does not block the normal line of sight the same principle and general night vision , In the case of a glimmer of light outside the scene with a multiplier tube to enhance the brightness of the scene brightness to 1 million -2.5 million times on the screen showed a clearer picture of the night vision of the structure as shown below, Binoculars, each with an objective lens assembly, a sight multiplier tube assembly and an eyepiece assembly, are attached to the transversely moving assembly. The sight multiplier assembly is an internal field replaceable assembly (SRU) Sight multiplier tube and integrated power supply, both of which are precisely housed in the acetal shell to ensure that the incident surface coincides with the objective image plane at infinity. The objective lens assembly is also replaceable in the infield with seven
