Abstract

Modern multi-camera computational imaging can enable new levels of performance beyond what is possible using conventional single-aperture imaging. We will report recent research that demonstrates how multi-camera computational imaging enables low-cost thermal-infrared imaging through 2pi steradians combined with three-dimensional imaging through obscurations. Modern consumer electronics commonly employ multiple cameras to provide multiple fields of view: we will describe how, for the first time, high-resolution imaging can be attained using an array of anamorphic cameras. Microscopy traditionally involves a trade of field of view, spatial resolution and depth of field: we show how multi-camera Fourier-ptychographic microscopy enables sub-micron gigapixel microscopy with a depth of field that is two orders-of-magnitude greater than using conventional microscopy.
