One-Dimensional High-Resolution Wavefront Sensor Enabled by Subwavelength Compound Gratings
Angle sensors are widely used for wavefront measurements, which is attributed to their integration and robustness. Currently, commercial sensors are available with pixel sizes in the order of wavelengths. However, the spatial resolution of angle sensors still lags far behind. Here, we report a one-d...
