Authors: Zhaowei Chena, Ryan Luua, Robert E. Parksb, Surya Prakash Gurunarayananc, and Daewook Kima,* ABSTRACT We present a deep-learning-based phase-retrieval framework that uses Bessel-beam illumination to extend the recoverable aberration range in wavefront sensing. By exploiting the large effective numerical aperture and extended depth of focus of Bessel beams, the proposed method increases the range […]
