我们提出了线性焦平面技术(LIFT),并将其与经典的传感器,如四单元波前传感器(WFS),金字塔WFS和夏克哈特曼WFS进行比较。由LIFT感测的模式的数量可以在没有任何硬件修改或低阶感测性能的降级的情况下被调谐。我们推导出一个分析模型的噪声传播规律,我们验证端到端的模拟。
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.
