Detector-Conditioned Source-Space Nulls and Null-Mask Loss in a Programmable Two-Slit Interferometer
Jianming Wen
Afshar's double-slit experiment probes wave--particle complementarity by placing a wire grid at the dark fringes of a downstream interference pattern while retaining an imaging bas…
Fixed-detector tilt--defocus sensing by upstream source coding in a time-reversed Young interferometer
Jianming Wen
We propose a physically explicit sensing application of a time-reversed Young (TRY) interferometer: simultaneous monitoring of beam tilt and focus drift with a fixed detector. The…
Entropic Reciprocity in Time-Reversed Young Interferometry
Jianming Wen
We show that time-reversed Young interferometry reorganizes, rather than reverses, optical entropy. A fixed detector conditions the reciprocal source--detector Green function and p…
Multi-slit time-reversed Young interference: source-space grating laws, quadratic-phase effects, and Talbot-like revivals
Jianming Wen
We develop a compact theory of time-reversed Young (TRY) interference beyond the symmetric two-slit geometry by considering equally spaced three-slit, finite -slit, and infinite…
