Abstract: A laser-based altimeter for use on-board an aircraft comprises: a first housing including a hollow cavity and an exit aperture, and a second housing including a hollow cavity and an entrance aperture. A laser source and a plurality of first optical elements are fixedly supported in a compact configuration within the hollow cavity of the first housing. The plurality of first optical elements directs laser beams generated by the laser source from a first optical path to a second optical path which exits the first housing through the exit aperture. At least one second optical element is configured within the hollow cavity of the second housing to form a telescope with a predetermined field of view. The telescope receives at the entrance aperture reflections of the pulsed laser beams from objects within the field of view thereof and focuses the received reflections substantially to a focal point. A light detector is included for receiving and converting the focused reflections into electrical signals representative thereof. The first and second housings are fixedly secured in alignment with respect to each other to permit the second optical path of the pulsed laser beams to be adjusted within the field of view of the telescope. A mirror apparatus is the only first optical element of the plurality that is fixedly adjustable for directing the second optical path within the field of view of the telescope, the mirror apparatus being lockable in place after final adjustment. The first and second housings may be part of a common housing.
Abstract translation: 一种用于在飞机上使用的基于激光的高度计，包括：包括空腔和出口孔的第一壳体以及包括中空腔和入口孔的第二壳体。 激光源和多个第一光学元件以紧凑的构造固定地支撑在第一壳体的空腔内。 多个第一光学元件将由激光源产生的激光束从第一光路引导至通过出口孔离开第一壳体的第二光路。 至少一个第二光学元件被配置在第二壳体的空腔内以形成具有预定视场的望远镜。 望远镜在入射孔处接收来自其视场内的物体的脉冲激光束的反射，并将接收到的反射基本上聚焦到焦点。 包括光检测器，用于接收聚焦反射并将其转换成代表其的电信号。 第一和第二外壳相对于彼此固定固定，以允许脉冲激光束的第二光路在望远镜的视场内被调节。 反射镜装置是多个固定可调的第一光学元件，用于将第二光路引导到望远镜的视场内，反射镜装置在最终调节后可锁定在适当位置。 第一和第二壳体可以是公共壳体的一部分。
