Abstract

A quantum-imaging system for detecting photons, including short-wavelength (<1 nm) photons, is provided. A quantum imaging system can include optical read-out and optical means, and can be configured to perform as both a photon counter and a photon spectrometer. A quantum-imaging system can function as a photon counter and be configured to measure photon beam fluences (e.g., in J/cm2) for both strong beams and weak beams, the latter ones, for example, in the intensity range of 1 pJ/cm2sec, or 0.1 μSv/h. The quantum-imaging system can also function as a photon spectrometer and can be configured to measure photon energies with high energy resolution such as, for example, 1% of photon energy.
