  • Spectroscopy apparatus and method
    Patent number: 10031398
    Abstract: There is presented a spectroscopic apparatus and method wherein an input light source that inputs pump light to a photon pair source. The photon pair source converts pump photons into signal and idler photon pairs. The photon pair source is, in some of examples described herein, tuneable so that the wavelength of the signal and idler photons can be changed by application of a tuning means. At least one of the signal and idler photons is made incident upon a medium under test. A heralding detection apparatus is used to detect any signal and idler photons output from the spectroscopy apparatus, wherein at least one of the photons of the pair has interacted with or been operated upon by the medium under test.
