Nettetfaces. Stellar amplitude (Michelson) interferometry (SAI) was employed (very simply) in the 1920’s tomeasure afew coolstars, but thetechnique was strongly control-technology-limited. In the 1960’s, stellar intensity interferometry (SII) was employed to measure some 32 stars [13], but it was, at that time, very sensitivity-limited.

Nettet19. apr. 2024 · Intensity interferometry, on the other hand, correlates only photon fluxes and can thus support much larger numerical apertures, but suffers from a reduced signal due to the low average photon number per mode in thermal light. It has hitherto not been clear which method is superior under realistic conditions. NettetIntensity Interferometry is based on the Hanbury Brown and Twiss effect (HBT hereafter; Hanbury Brown & Twiss 1956) that relates the bunching of photons in the intensity …
