WebJul 16, 2024 · An interesting application for COACH is incoherent imaging with synthetic aperture (SA). SA is a familiar super-resolution method and a conventional technique in astronomy to accomplish image resolution beyond the diffraction limit dictated by the physical aperture [ 47] of the telescope. WebImaging with an optical incoherent synthetic aperture (SA) means that the incoherent light from observed objects is processed over time from various points of view to obtain a resolution equivalent to single-shot imaging by the SA …
