Broadband imaging with one planar diffractive lens
Nabil Mohammad, Monjurul Meem, Bing Shen +1
We demonstrate imaging over the visible band using a single planar diffractive lens. This is enabled via multi-level diffractive optics that is designed to focus over a broad wavel…
An Ultra-compact Nanophotonic Optical Modulator using Multi-State Topological Optimization
Apratim Majumder, Bing Shen, Randy Polson +2
Optical modulators are one of the most important elements of photonic circuits. Here, we designed, fabricated and characterized a nanophotonic all optical modulator (NOM) in silico…
Lensless-camera based machine learning for image classification
Ganghun Kim, Stefan Kapetanovic, Rachael Palmer +1
Machine learning (ML) has been widely applied to image classification. Here, we extend this application to data generated by a camera comprised of only a standard CMOS image sensor…
Computational snapshot angular-spectral lensless imaging
Peng Wang, Rajesh Menon
By placing a diffractive element in front of an image sensor, we are able to multiplex the spectral and angular information of a scene onto the image sensor. Reconstruction of the…
Computational multi-spectral video imaging
Peng Wang, Rajesh Menon
Multi-spectral imagers reveal information unperceivable to humans and conventional cameras. Here, we demonstrate a compact single-shot multi-spectral video-imaging camera by placin…
Lensless Photography with only an image sensor
Ganghun Kim, Kyle Isaacson, Racheal Palmer +1
Photography usually requires optics in conjunction with a recording device (an image sensor). Eliminating the optics could lead to new form factors for cameras. Here, we report a s…
