Collaborative On-Sensor Array Cameras
Jipeng Sun, Kaixuan Wei, Thomas Eboli +6
Modern nanofabrication techniques have enabled us to manipulate the wavefront of light with sub-wavelength-scale structures, offering the potential to replace bulky refractive surf…
Large-Area Fabrication-Aware Computational Diffractive Optics
Kaixuan Wei, Hector A. Jimenez-Romero, Hadi Amata +4
Differentiable optics, as an emerging paradigm that jointly optimizes optics and (optional) image processing algorithms, has made innovative optical designs possible across a broad…
Beating bandwidth limits for large aperture broadband nano-optics
Johannes E. Fröch, Praneeth K. Chakravarthula, Jipeng Sun +10
Flat optics have been proposed as an attractive approach for the implementation of new imaging and sensing modalities to replace and augment refractive optics. However, chromatic a…
Thin On-Sensor Nanophotonic Array Cameras
Praneeth Chakravarthula, Jipeng Sun, Xiao Li +6
Today's commodity camera systems rely on compound optics to map light originating from the scene to positions on the sensor where it gets recorded as an image. To record images wit…
