    • A multi-function day/night observation, ranging, and sighting device includes a single objective lens group and a single eyepiece lens and provides an image of a scene. The single objective lens group leads to a visible-light first optical path and to an invisible-light second optical path. It will be understood that the terms visible-light and invisible-light are used merely to distinguish the two optical paths, and not as a limitation. In other words, some visible light will pass to the image intensifier tube, and this tube is capable of providing an image in response to light in the visible portion of the spectrum. On the other hand, some light in the infrared portion of the spectrum may pass along the visible-light optical path. As mentioned, the invisible-light second optical path includes an image intensifier tube providing a visible image. The first and second optical paths converge with visible images provided by each pathway being overlaid at a reticule plane. A single light path leads from the reticule plane to the eyepiece lens. A laser provides a pulse of laser light projected into the scene via the single objective lens, and the image intensifier tube is used as a detector for a portion of the laser light pulse reflected from an object in the scene in order to provide a laser range finding function. The device includes a light-emitting display visible through the eyepiece lens and providing ranging information superimposed over the image of the scene as seen by a user of the device. Methods of the device's operation are also disclosed.
    • 多功能日夜观察,测距和瞄准装置包括单个物镜组和单个目镜,并提供场景的图像。 单个物镜组导致可见光第一光路和不可见光第二光路。 应当理解,术语可见光和不可见光仅用于区分两个光学路径,而不是限制。 换句话说,一些可见光将传递到图像增强管,并且该管能够响应于光谱的可见部分中的光而提供图像。 另一方面,光谱的红外部分中的一些光可以沿着可见光光路通过。 如上所述,不可见光第二光路包括提供可视图像的图像增强管。 第一和第二光路与由每个路径提供的可见图像重叠在网状平面上会聚​​。 单个光路从网状平面导向目镜。 激光器通过单个物镜提供投射到场景中的激光脉冲,并且图像增强管被用作从场景中的物体反射的激光光脉冲的一部分的检测器,以提供激光范围 发现功能。 该装置包括通过目镜透镜可见的发光显示器,并且提供叠加在场景的图像上的测距信息,如装置的用户所看到的。 还公开了设备操作的方法。
