  • Quantum imaging with undetected photons
    Patent number: 9557262
    Abstract: A method comprises: generating a first and a second correlated photon beam with wavelengths ?1 and ?2, respectively, wherein preferably ?1??2; separating the first photon beam and the second photon beam; illuminating an object with the first photon beam; generating a third and a fourth correlated photon beam with wavelength ?1 and wavelength ?2, respectively; overlapping the first photon beam with the third photon beam such that photons of wavelength ?1 in either photon beam are indistinguishable; overlapping the second photon beam with the fourth photon beam such that photons of wavelength ?2 in either photon beam are indistinguishable; and using the overlapped photons of wavelength ?2 for imaging and/or spectroscopy of the object such that the photons that illuminate the object are not detected.
