Experimental Demonstration of Double-Fourier Interferometer Imaging for Future Space-Based Far-Infrared Observatories
Far-infrared (FIR) astronomy is crucial for observing star formation, active galactic nuclei, and protoplanetary systems, but its effectiveness is severely limited by poor diffraction-limited spatial resolution. To overcome this limitation, a double-Fourier interferometer (DFI), which couples a spatial interferometer w...
