    • At least one second beam of light from a first beam of light generated by a laser is directed into an atmosphere. Light therefrom scattered by molecules or aerosols in the atmosphere is collected by at least one telescope as at least one light signal, which together with a reference beam from the first beam of light are simultaneously processed by an interferometer, and resulting fringe patterns are imaged onto a detector adapted to output a resulting at least one signal responsive thereto. In various aspects: a plurality of transversely separated light collectors collected the scattered light; at least two telescopes are associated with a common second beam of light; or the telescope is coupled to a gimble mount that provides for positioning a region of overlap of the second beam of light with the field of view of the telescope.
    • 来自由激光产生的第一光束的至少一个第二光束被引导到大气中。 由大气中的分子或气溶胶散射的光由至少一个望远镜收集为至少一个光信号,其与来自第一光束的参考光束一起被干涉仪同时处理,并将所得到的条纹图案成像到 检测器,适于响应于此而输出所得到的至少一个信号。 在各个方面:多个横向分离的收集器收集散射光; 至少两个望远镜与公共第二光束相关联; 或者望远镜耦合到一个能够将第二光束与望远镜的视场的重叠区域定位的微型安装座。

In various aspects: a data processor gates the signal to provide a range-responsive measurement; the light signal is multiplexed; a circle-to-line interferometer optic transforms an at least partially circular fringe pattern to a substantially linear fringe pattern; or a CCD detector provides for recording a range-resolved image by successively transferring charges from one adjacent row of photosites to another.
