In this talk I will discuss the results of temporal intensity interferometry observations on three stars using a 1m optical telescope at OCA-Calern observatory. To our knowledge this is the first successful on sky experiments following the pioneering work of Hanbury Brown et al, in 1960’s and 1970’s.
We have performed laboratory test on atomic vapours and then used the photon counting detection bench to measure the temporal correlation function g(2)(0) on three different stars.
