SUMMARY
The discussion centers on the concept of subtractive mode intensity interferometry as an alternative to traditional methods used in Hanbury-Brown and Twiss (HBT) experiments. It proposes that by subtracting intensity signals from two detectors, one could observe a transition from RMS noise addition at greater distances to a null result when the detectors are nearly coincident. While this approach may not be optimal, the feasibility of its implementation is questioned and explored.
