Claim Text:
1. A processing method for a spectrometric measurement in terms of energy of a photon flux received by a photosensitive element of a detector, the method comprising the following successive steps: converting each photon received by the photosensitive element into packets of electrical charges and converting said packets of electrical charges in an electrical signal with a preamplifier, a characteristic of which is representative of the energy of the photon considered, filtering each electrical signal with a first low-pass filter of a shaping circuit whose cutoff frequency is adjusted as a function of the photon flux received by the photosensitive element, such that the greater the flux, the higher the cutoff frequency, determining a characteristic of each filtered electrical signal with a measurement circuit, generating an energy spectrum for the photon flux received with a spectrum generator as a function of the characteristic of the filtered electrical signals, and filtering an energy spectrum with a second low-pass filter being a low-pass filter of a smoothing filter whose cutoff frequency is adjusted as a function of the photon flux provided by the spectrum generator, such that the greater the flux, the lower the cutoff frequency.
