Paper Abstract

We present an alternative imaging technique using spectrally resolved longitudinal spatial coherence interferometry to encode a scene’s angular information onto the source’s power spectrum. Fourier transformation of the spectrally resolved channeled spectrum output yields a measurement of the incident scene’s angular spectrum. Theory for the spectrally resolved interferometric technique is detailed, demonstrating analogies to conventional Fourier transform spectroscopy. An experimental proof of concept system and results are presented using an angularly-dependent Fabry-Perot interferometer-based optical design for successful reconstruction of one-dimensional sinusoidal angular spectra. Discussion for a potential future application of the technique, in which polarization information is encoded onto the source’s power spectrum is also given.
