Summary
Extending calculations carried out before (3), the present paper is dealing with the exact statistics of the fluctuation of wave trains emitted by a source the extension of which cannot be neglected. As before the individual wave trains are supposed to decay exponentially, however, it is assumed here that the individual trains have different frequencies, intensities and polarization. Various experimentally observed effects, among them that obtained with the stellar interferometer by Hanbury Brown and Twiss (1) can be quantitatively accounted for.
Riassunto
Estendendo calcoli eseguiti prima della (3) il presente lavoro si occupa della statistica esatta della fluttuazione dei treni d’onde emessi da una sorgente di estensione non trascurabile. Come precedentemente, si assume che i singoli treni d’onde decadano esponenzialmente; tuttavia qui si assume che i singoli treni abbiano differenti frequenze, intensità e polarizzazioni. Vari effetti osservati sperimentalmente, fra cui quello ottenuto coll’interferometro stellare da Hanbury Brown e Twiss, si possono giustiflcare quantitativamente.
