TOM 2 Computational, Adaptive and Freeform Optics

From flat cameras to high resolution microscopy: beating aberrations with computational multi-camera imaging

Andrew Robert Harvey

University of Glasgow, United Kingdom

Biological evolution has yielded countless examples of multi-aperture imaging systems employing (biological) computational construction of images: ranging from compound insect eyes for wide-field vision, to our familiar binocular stereoscopic vision. We will describe how diversity in multiple-camera imaging can be exploited to yield conformal imaging from flattened structures; imaging with high space-bandwidth product, with extreme field of view and at low cost...

Spin glasses (SGs) are paradigmatic physical models whose dynamics computation is nondetermistic polynomial-time hard. Here we report on a recent implementation of the optical simulation of an SG, exploiting the N segments of a wavefront-shaping device to play the role of the spin variables, combining the interference downstream of a scattering material to realize the random couplings between the spins. In the optical SG, where interaction terms are realized simultaneously when the independent light rays interfere on the detector’s surface, we demosntrate a speedup, with respect to purely in-silico simulations, scaling with N.

TOM 2 Computational, Adaptive and Freeform Optics

An inverse model for two-dimensional reflectors with scattering

We present a novel approach of modelling surface light scattering in the context of freeform optical design. Using energy conservation, we derive an integral relation between the scattered and specular distributions. This integral relation reduces to a convolution integral in the case of isotropic scattering in the plane of incidence for cylindrically and rotationally symmetric problems.
