AI 中文摘要
空间日冕仪光学平台（SCoOB）是一款高对比度成像测试平台，旨在类空间真空环境下演示可见光波段的星光抑制技术。自上一次会议论文以来，该测试平台已完成重大组件升级，包括100%良品率的BMC Kilo-C变形镜、黑硅光瞳光阑，以及楔角基底间的圆偏振片。为评估折射光学元件诱导的横向色差带来的性能极限，我们开发了解析与数值工具以预测宽带对比度；此外，我们展示了该测试平台结合多传感波段隐式电场共轭用于宽带控制的宽带对比度性能。
英文摘要
The space coronagraph optical bench (SCoOB) is a high contrast imaging testbed designed to demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuum environment. Since the previous proceedings, the testbed has undergone major component upgrades, including a 100%-yield BMC Kilo-C deformable mirror, a black silicon pupil stop, and circular polarizers between wedged substrates. To assess the performance limits imposed by lateral chromatic aberration induced by refractive optical elements, we develop analytic and numerical tools to predict the broadband contrast. Additionally, we present the broadband contrast performance of the testbed using implicit electric field conjugation with multiple sensing bands for broadband control.
