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…
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…
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,…
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…
