Claim Text:
1. A Natural Light Interferometer, comprising: an apparatus for generating a facsimile signal (genight) from an incident natight carrying the frequency information of the natight but frequency shifted by a small, constant value, that can be physically separated from the natight; a phase modulation device capable of impressing one of more specific spatpats onto the genight; signal transport optics appropriate to the wavelength regime in which the NLI, wherein the NLI is a natural light interferometer, is operating such as mirrors, lenses and beamsplitters; a single element square law detector appropriate to the wavelength regime in which the NLI is operating in which to mix the natight and genight signals; a complex current measuring device to measure the detector IF, wherein IF is an interference frequency, output; a data storage device; a computer with software or firmware capable of reconstructing the natight amphat using the data generated by the detector and stored on the storage device.
