Performance of dispersed Rayleigh interferometer on the active cophasing and alignment testbed

We report the laboratory experiment on a segmented mirror testbed that shows the use of a dispersed Rayleigh interferometer to phase segmented mirrors. Segment alignment of tip-tilt is fulfilled by overlapping diffraction pattern centroids of the three individual segments on the focal plane. A spherical interferometer is introduced to evaluate the performance of piston, tip-tilt sensing, and control closed-loop, and finally a total residual root-mean-square (RMS) surface error of about 45 nm is

引用\[1\]:在这个上下文中，phase alignment指的是时钟相位对齐。时钟相位对齐是指确保多个时钟信号在特定的时刻到达目标设备的过程。在这个问题中，phase alignment是指输入时钟的相位对齐问题。具体来说，当使用COMPENSATION mode ZHOLD时，要求pll/inst/mmcm_adv_inst/CLKIN1引脚和pll/inst/mmcm_adv_inst/CLKIN2引脚具有相同类型的时钟驱动器。也就是说，pll/inst/clk_in1_clk_pll引脚和pll/inst/clk_in2引脚必须具有相同类型的时钟驱动器。这个问题可能是由于设置了第二个输入时钟而导致的。 #### 引用[.reference_title] - *1* [求助 [DRC PDRC-150] Input clock phase alignment](https://blog.csdn.net/qq_39035910/article/details/123275835)[target="_blank" data-report-click={"spm":"1018.2226.3001.9630","extra":{"utm_source":"vip_chatgpt_common_search_pc_result","utm_medium":"distribute.pc_search_result.none-task-cask-2~all~insert_cask~default-1-null.142^v91^control,239^v3^insert_chatgpt"}} ] [.reference_item] [ .reference_list ]
