摘要
本文介绍了为太平洋海底神瑤实验（P-ONE）设计和性能表征的光学校准系统。这些系统包括基于硅氮化物场效应晶体管技术的新型光脉冲驱动电路及其用于方向性和各向同性自监控光学校准仪器的应用。为该实验的首条线生产了 330 个方向性光脉冲器和两个直径 17 英寸的各向同性校准模块（P-CAL）。我们展示了方向性和各向同性校准装置的设计与性能，并对两批完整生产的器件进行了详细的光学表征。在 365-520 nm 的波长范围内，所开发的驱动电路实现了最高达 光子的发射强度和最小 1.4 ns 的脉冲宽度。光脉冲驱动器和 P-CAL 中的自监控电子采用相同的实验 setup 进行表征，并结合专用的 GEANT4 仿真框架对该仪器的光学各向同性设计进行了优化。经优化后的 P-CAL 在整个 球面角范围内实现了模拟各向同性等级为 。这些仿真研究结果通过在空气和水中分别使用两个独立的实验 setup 进行专门测量得以明确验证。基于此，对 P-ONE 部署的 P-CAL 模块的详细性能预估得以实现。
