Abstract
The detector of the invention relates to the field of X or gamma photon detection. It is particularly adapted as a measuring chamber in conventional radiology and as a detector in scanography. It comprises at least one transformer for transforming X or gamma photons into light photons and at least one transformer for transforming light photons into electric signals representative of the energy of the incident X or gamma photons. The transformer for transforming X or gamma photons into light photons comprises a photoconducting layer and an electroluminescent layer between two electrodes which are brought to a biasing potential. The transfer electrode may be formed by a Schottky barrier. The transformer for transforming light photons into signals comprises a photosensitive layer, as a photovoltaic cell, on a substrate.
