摘要	A method and apparatus for rapid measurements of far-field radiation profiles having a large dynamic range from an optical source is disclosed. Some embodiments of the apparatus include a collector coupled to a rotating hub so that the rotation of an entrance to the collector defines a plane, a detector coupled to receive light captured at the entance to the collector, and detector electronics having a programmable gain coupled to receive a signal from the detector. In order to obtain a large dynamic range, far-field data from the optical source is taken at a number of gain settings of the detector electronics and a compiled far-field radiaton profile is constructed. Characterizing parameters for the optical source, such as fiber parameters for an optical fiber, can be calculated based on the compiled far-field radiation profile.
其他摘要	公开了一种用于快速测量具有来自光源的大动态范围的远场辐射分布的方法和设备。该装置的一些实施例包括耦合到旋转毂的收集器，使得收集器的入口的旋转限定平面，耦合以接收在收集器处捕获的光的检测器，以及具有耦合到的收集器的可编程增益的检测器电子器件。从探测器接收信号。为了获得大的动态范围，来自光源的远场数据是在检测器电子设备的多个增益设置下获得的，并且构建了编译的远场辐射分布。可以基于编译的远场辐射分布来计算光源的特征参数，例如光纤的光纤参数。
