Abstract
A singlet imaging system for imaging an object onto a detector includes a lens configured for producing transverse ray intercept curves which are substantially straight, sloped lines. A wavefront coding element is formed on a surface of the lens and configured such that a modulation transfer function of the lens and wavefront coding element, combined, exhibits reduced variation, over a range of spatial frequencies and caused, at least in part, by aberrations of the lens, as compared to a modulation transfer function of the lens alone, without the wavefront coding element. A post processor is configured for generating an improved modulation transfer function, over the range of spatial frequencies, as compared to the modulation transfer function of the lens and the wavefront coding element.
