X ray imaging can benefit from dynamic range enhancement methods developed initially for visible and infrared CMOS pixel sensors. An X-ray pixel design based on the folded multiple capture technique is presented. The influence of spatial and temporal noise on the determination of the photocurrent is discussed. The dynamic range can exceed 100db.
Spectroscopic measurements are presented using the PID350 pixelated gamma radiation detectors. A high-speed data acquisition system has been developed in order to reduce the data loss during the data reading in case of a high flux of photons. A data analysis framework has been developed in order to improve the resolution of the acquired energy spectra, using specific calibration parameters for each...
Simulation studies and spectroscopic measurements are presented regarding the development of a pixel multilayer CdTe detector under development in the context of the COCAE project. The instrument will be used for the localization and identification of radioactive sources and radioactively contaminated spots. For the localization task the Compton effect is exploited. The detector response under different...
