先进天文仪器需要可访问、可重构的平台,以便在天基部署前验证新技术与算法。本文介绍夏威夷实验工程实验室(He'e-Lab)的设计、架构与对准验证,这是一个最先进的模块化测试平台,专注于两个互补研究方向:(A)实时计算回路内天文光子学组件的集成与表征;(B)高级波前传感与控制(WFS&C)算法的开发。该测试平台配备宽带超连续谱光源(500纳米至2微米)、1000致动器的波士顿微机械高次变形镜,以及提供活塞-倾斜- tip-tilt控制的37段六边形镜组件,用于模拟凯克望远镜、詹姆斯·韦伯空间望远镜(JWST)等分段孔径。下游能力包括HASO 126夏克-哈特曼传感器、由CACAO软件包驱动的实时计算环境,以及耦合到可见光谱仪(R=3000)的模块化注入平台。本文报告系统对准成功,并概述即将开展的自适应光学与光子器件验证框架的路线图。
英文摘要:
Advanced astronomical instrumentation requires accessible, reconfigurable platforms to validate novel technologies and algorithms before on-sky deployment. We present the design, architecture, and alignment validation of the Hawaii Experimental Engineering Lab (He'e-Lab), a state-of-the-art modular testbed dedicated to two complementary research tracks: (A) the integration and characterization of astrophotonics components within a real-time computing loop, and (B) the development of advanced wavefront sensing and control (WFS&C) algorithms. The testbed features a broadband supercontinuum source (500 nm to 2 microns), a high-order 1k-actuator Boston Micromachines deformable mirror, and a 37-segment hexagonal mirror assembly providing piston-tip-tilt control to emulate segmented apertures like Keck and JWST. Downstream capabilities include a HASO 126 Shack-Hartmann sensor, a real-time computing environment driven by the CACAO package, and a modular injection platform coupled to a visible-wavelength spectrograph (R3, 000). We report on the successful system alignment and outline the roadmap for upcoming adaptive optics and photonic device validation frameworks.
