Toward Ultralightweight Remote Sensing With Harmonic Lenses and Convolutional Neural Networks.

In this paper, we describe our advances in manufacturing a 256-layer 7-μm thick harmonic lens with 150 and 300 mm focal distances combined with color correction, deconvolution, and a feedforwarding deep learning neural network capable of producing images approaching photographic visual quality. While reconstruction of images taken with diffractive optics was presented in previous works, this paper...
