Fast first-photon ghost imaging
Webthe single photon counting modules (SPCM’s) and the 780 nm longpass -colored glass filters were inserted in front of these collimators. The filter allowed only the light with a wavelength longer than 780 nm to pass through it. Then, the 810 nm photon pairs were sent to the detectors and B on the A SPCM via multimode fiber path cables. WebNov 6, 2015 · Fast first-photon ghost imaging. 22 March 2024.
