当测量具有大像差的波前时,串扰效应大大限制了基于全息的模式波前传感(HMWS)的能力。在这方面的贡献,我们引入了一个曲率为基础的测量技术到HMWS通过紧凑的全息设计来扩展的动态范围和灵敏度的HMWS。如果输入像差较大,则首先经由曲率感测来检测主要像差模式,并使用波前校正装置(例如,膜反射镜)来补偿。然后系统切换到HMWS以获得更好的灵敏度和精度,同时降低像差。不同的方法重建的波前进行了测试和广泛的模拟不同的像差进行了分析。
The crosstalk effect considerably limits the capability of holography-based modal wavefront sensing (HMWS) when measuring wavefronts with large aberrations. In this contribution, we introduce a curvature-based measurement technique into HMWS to extend the dynamic range and the sensitivity of HMWS via a compact holographic design. If the input aberrations are large, the dominating aberration modes are first detected via curvature sensing and compensated using a wavefront correcting device, e.g. a membrane mirror. The system then switches to HMWS to obtain better sensitivity and accuracy with reduced aberrations. Different approaches for the reconstruction of the wavefront have been tested and extensive simulations for different aberrations have been analyzed.
