We propose the linearized focal-plane technique (LIFT) and compare it to classical sensors, such as the quad-cell wavefront sensor (WFS), pyramid WFS, and Shack-Hartmann WFS. The number of modes sensed by LIFT can be tuned without any hardware modification nor degradation of low-order sensing performance. We derive an analytic model of the noise propagation law, which we validate on end-to-end simulations.
我们提出了线性化焦面技术(LIFT),并将其与传统传感器,如四元细胞波前传感器(WFS)、金字塔 WFS 和 Shack-Hartmann WFS 进行了比较。LIFT 感测的模式数量可以在不进行任何硬件修改或降低低阶感测性能的情况下进行调整。我们推导出了噪声传播规律的解析模型,并通过端到端模拟进行了验证。
