Intensity interferometry-based 3d imaging
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. NettetThe constant of proportionality is given by the speed of light c. from publication: Intensity interferometry-based 3D imaging The development of single-photon counting detectors and arrays has ...

We propose a new approach, based on the Hanbury Brown and Twiss intensity interferometry, to transform a Cherenkov telescope to its equivalent optical telescope. We show that, based on the use of photonics components borrowed from quantum-optical applications, we can recover … 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 …
NettetAbstract: Interferometers are widely used in imaging technologies to achieve enhanced spatial resolution, but require that the incoming photons be indistinguishable. In previous work, we built and analyzed color erasure detectors which expand the scope of intensity interferometry to accommodate sources of different colors.
