We demonstrate a bio-inspired coating for novel imaging and sensing designs: the coating sorts different colors and linear polarizations. This coating, composed of conducting, nanofibrous polyaniline in an inverse opal film (PANI-IOF), is inexpensive

We study encoded diffraction with shallow neural networks using singular value decomposition entropy (H SVD ) to measure image span. Higher-H SVD synthetic training images are learned more slowly; their generalized models generally attain higher reco

Speed, generalizability, and robustness are fundamental issues for building lightweight computational cameras. Here we demonstrate generalizable image reconstruction with the simplest of hybrid machine vision systems: linear optical preprocessors com

The stability of an inverse-problem solver depends on algorithm computational complexity. We demonstrate generalizable image reconstruction with the simplest of hybrid machine vision systems: fixed, linear optical preprocessors combined with no-hidde

Hybrid vision systems may enable real-time image processing in remote, power/energy-limited applications. We demonstrate 40k/17k frame-per-second self-motion inference rates with optical processing, which is 3 orders of magnitude faster than current

Here we elaborate on the edge-enhanced spectral components that are produced by the vortex Fourier trans- form, which are introduced in [1]. The vortex phase pattern imprinted on from an object breaks the spatial invariance of its Fourier representat

We demonstrate an optics pipeline for classical computer-vision autoencoders, which are a reliable de-noising defense against adversarial attacks. With vortex Fourier encoding, we show results with 10 nJ/cm2 illumination.

We demonstrate diffractal spatial multiplexing for wireless communication for moving transceivers. The approach leverages free-space diffraction with optical demodulation schemes. Exponentially-enhanced data rates are achieved without tracking.

Deep learning convolutional neural networks generally involve multiple-layer, forward-backward propagation machine-learning algorithms that are computationally costly. In this work, we demonstrate an alternative scheme to convolutional neural nets th

We studied the degradation of thermal conductivity in single crystal sapphire (α-Al2O3) irradiated by 167 MeV Xe swift heavy ions (SHIs) over the multiple fluences in the range of 1012–1014 ions/cm2. Thermal conductivity was measured primarily in
