"accurate and precise ranging of a remote object situated far beyond coherence time dictated by light source's spectral bandwidth... thermal light source, e.g. sun, interacting with double slit mask with 2 slits A and B separated beyond coherent length of source, and 2 cameras... object distance encoded and retrieved through spatially correlated measurements... robust to turbulence and ambient noise... autonomous vehicles, robotics, environmental monitoring"
