Attaining the quantum limit of superresolution in imaging an object's length via predetection spatial-mode sorting
Physical Review A
Recent work considered the ultimate (quantum) limit of the precision of estimating the distance between two point objects. It was shown that the performance gap between the quantum limit and that of ideal continuum image-plane direct detection is the largest for highly sub-Rayleigh separation of the objects, and that a pre-detection mode sorting could attain the quantum limit. Here we extend this to a more general problem of estimating the length of an incoherently radiating extended (line)doi:10.1103/physreva.99.033847 fatcat:hrc2gr3b5jgwrgshwtrxyl6rq4
