Paper Abstract
Diffractive optical systems in the Infrared (IR) wavelength regime are being re-examined for remote sensing
applications. A pupil-plane adaptive coded aperture can enable a fine resolution, wide field of view sensor system
without mechanical scanning. Due to the relatively long wavelengths, coded aperture systems in the IR have unique
issues in regards to e.g. X-ray coded apertures. These include diffraction effects, wavelength dependence of optical
elements, off axis aberrations due to thick screens, etc. In this paper, we provide a general system model framework
based on partial coherence theory that enables us to explore many of the technical challenges in IR diffractive
imaging. This paper develops the general theory and shows examples of issues that impact the optical transfer
function (OTF) and impulse response of these types of architectures.
