Abstract
A system that performs heterodyne optical imaging across multiple platforms gathers an optical signal from an optical sensor at each of the multiple platforms. At the same time, an optical frequency comb local oscillator (LO) at each of the platforms generates a reference comb signal comprising a set of optical frequency comb lines at different frequencies, wherein each optical frequency comb LO is locked to a local atomic clock at each of the platforms. Next, a mixer, at each of the platforms, is used to mix the optical signal gathered from the optical sensor with the reference comb signal generated by the optical frequency comb LO to generate a mixed signal. The system then communicates the mixed signals generated at each of the platforms to a central location. Finally, the system correlates the mixed signals received from each of the platforms and generates a reconstructed optical image.
