We present and discuss recent research aiming at fast, cost-effective, and easy-to-use spectral imaging. Methodologies presented include using a stereoscopic camera with additional optical filters, extending the color filter array beyond RGB, and illuminant estimation.

We distinguish geometric cell structures using a deformable mirror for high-throughput, label-free flow cytometry, overcoming approaches that can result in undesirable chemical modifications or low throughput.

The customary way in which spectral imagers are specified does not give a proper account of important performance characteristics. Suggestions are given for an improved set of performance characteristics, particularly with respect to noise and coregistration.

With its three vertically stacked photodiodes, the Foveon X3 image sensor enables direct captures of red, green and blue light at each pixel in an image during a single exposure. It greatly reduces computational time for interpolation for missing colors in conventional Bayer sensors and therefore color aliasing. Meanwhile, with the new Super-Fine Detail (SFD) exposure mode, cameras equipped with Foveon X3 technology can capture as many as 51 megapixel-equivalent noiseless images with an extensive dynamic range.

We investigate holographic imaging through extended scattering media in the extreme limit when small numbers of ballistic photons are present. Strong dependence of image quality on ratio of reference and signal beam powers is revealed.

A 360-degree light field recording system is proposed with a handheld light field camera and flat mirrors. A compact and one-shot light field capturing system is proposed in this paper. The overall studio consists of one commercialized light field camera and a couple of reflective plates. Without mechanical movement, light field from back and side parts of subjects is captured through a pair of mirrors. Owing to relatively large depth of focus of light field camera, a subject and its reflected images can be recorded on an image sensor. A position and orientation of mirrors are analyzed to optimize 360-degree light field recording. Experimental results are shown to verify the proposed recording system.
