Paper Abstract

Multichannel sampling strategies have been considered for a number of applications including feature specific imaging, and digital superresolution. Typically, channel coding is accomplished with a thin modulating mask, either in the focal plane, or in the aperture of the imaging system. In this contribution, we extend the concept of multichannel imaging to systems by suggesting the use of 3D structures for channel coding. A single pixel camera design and the single scattering approximation are used to obtain a Fourier space interpretation of 3D filters. The k-space analysis indicates that the dispersion relation of propagating plane wave modes set severe constraints if 3D filters are used for channel coding. We relate this to the broader questions about the fundamental limits of optical and computational imaging and propose 3D filters for wavelength coding and superresolution applications.
