光束阵列全孔径强度相干合成的顺序锁相方案
Sequential phase locking scheme for a filled aperture intensity coherent combination of beam arrays
摘要：
提出了一种新的用于光束阵列相干合成的相位锁定方案。采用类似于LOCSET的不同波束的相位抖动机制，重复使用顺序组合步骤的抖动频率。通过应用附加的相位交替方案，这允许使用标准的同步多通道锁定电子器件来锁相大量通道，即使在所采用的相位致动器的频率带宽受限时也是如此。
英文摘要：
We present a novel phase locking scheme for the coherent combination of beam arrays in the filled aperture configuration. Employing a phase dithering mechanism for the different beams similar to LOCSET, dithering frequencies for sequential combination steps are reused. By applying an additional phase alternating scheme, this allows to use standard synchronized multichannel lock-in electronics for phase locking a large number of channels even when the frequency bandwidth of the employed phase actuators is limited.
