    摘要: The invention relates in particular to a detector for two-dimensional analysis of a flux of photons or neutral particles. The detector comprises a solid plane converter (5) constituted by a two-dimensional matrix of cells (such as 9c), an array of charge-multiplying wires (6) using stimulated ionization of a gas, and a cathode grid (7). The cells both convert the photons or neutral particles and collect the charge, and the ionization is preferably stimulated until self-regulating streams of electrons appear (streamer mode).The invention has application to imaging devices.

    摘要: The object's transmission function is expressed as a finite power expansion of a reference-material reference thickness, each expansion power being equal to a ratio of a reference-material thickness to the reference thickness; the expansion coefficients are determined from the measurements of the intensities transmitted by the selected various thicknesses, including zero thickness, of the reference material exposed to a test beam evincing consecutively several energy spectra and from the measurements of the intensity transmitted by the object exposed to this same variable-spectrum test beam; the attenuation function is derived from the determination of the transmission function.
