Approaching quantum limits in sub-Rayleigh resolution using phase modulation optimization
Chao-Ning Hu, Jun Xin, Xiao-Ming Lu
Spatial-mode demultiplexing (SPADE) has made significant progress in incoherent optical imaging and has been implemented through various experimental approaches. Holography-based S…

Noise-robust discrimination of incoherent point sources with spatial-mode demultiplexing
Jian-Qiang Liu, Chao-Ning Hu, Jun Xin +1
We theoretically predict and experimentally demonstrate that a reduced spatial-mode demultiplexing (SPADE) measurement using only the two lowest-order Hermite-Gaussian modes exhibi…
