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.

We demonstrate a multimode detection system in a scanning laser ophthalmoscope (SLO) that enables simultaneous operation in confocal, indirect, and direct modes to permit an agile trade between image contrast and optical sensitivity across the retinal field of view to optimize the overall imaging performance, enabling increased contrast in very wide-field operation. We demonstrate the method on a wide-field SLO employing a hybrid pinhole at its image plane, to yield a twofold increase in vasculature contrast in the central retina compared to its conventional direct mode while retaining high-quality imaging across a wide field of the retina, of up to 200 deg and 20 μm on-axis resolution.
