A method for calibrating an ionizing radiation detector, with the aim of determining a correction factor in order to establish an amplitude-energy correspondence The invention first relates to a method for calibrating a device for detecting ionizing radiation, the detector comprising a semiconductor or scintillator detection material capable of generating a signal S of amplitude A upon interaction between ionizing radiation and the detection material, the method including the determination of a weighting factor of amplitude A.

Method for calibrating an ionising radiation detector and associated device

A method for calibrating an ionizing radiation detector, with the aim of determining a correction factor in order to establish an amplitude-energy correspondence. The invention first relates to a method for calibrating a device for detecting ionizing radiation, the detector comprising a semiconductor or scintillator detection material capable of generating a signal S of amplitude A upon interaction between ionizing radiation and the detection material, the method including the determination of a weighting factor at the amplitude A.

The invention is a method for estimating a cardiac frequency via the detection of radiation backscattered or transmitted by a bodily zone. The part is illuminated, simultaneously or successively, by light radiation extending over a first spectral band and a second spectral band. A photodetector detects radiation emitted by the bodily zone under the effect of its illumination, in each of the spectral bands. A first detection function and a second detection function are formed from the radiation detected in each spectral band, respectively. The method allows the cardiac frequency to be determined via the determination of characteristic instants that are identified from the first detection function and the second detection function simultaneously.
