Pupil Design for Computational Wavefront Estimation
Ali Almuallem, Nicholas Chimitt, Bole Ma +2
Establishing a precise connection between imaged intensity and the incident wavefront is essential for emerging applications in adaptive optics, holography, computational microscop…
Diffusion Algorithm for Metalens Optical Aberration Correction
Harshana Weligampola, Yuanrui Chen, Weiheng Tang +2
Metalenses offer a path toward creating ultra-thin optical systems, but they inherently suffer from severe, spatially varying optical aberrations, especially chromatic aberration,…
Direct Kernel Optimization: Efficient Design for Opto-Electronic Convolutional Neural Networks
Ali Almuallem, Harshana Weligampola, Abhiram Gnanasambandam +5
Hybrid opto-electronic neural networks combine optical front-ends with electronic back-ends to perform vision tasks, but joint end-to-end (E2E) optimization of optical and electron…
Wavefront Estimation From a Single Measurement: Uniqueness and Algorithms
Nicholas Chimitt, Ali Almuallem, Qi Guo +1
Wavefront estimation is an essential component of adaptive optics where the goal is to recover the underlying phase from its Fourier magnitude. While this may sound identical to cl…
