Resumen:
In this work we study the performance to obtain X-ray images of a Back Side Illuminated CMOS Image Sensor, the Omnivision OV5647, empoying X-rays from tube with a palladium anode and voltages from 7.5 keV to 50 keV. The performance is compared with the Timepix detector operating in the Time Over Threshold mode. False color images are obtained using data from different energies and brightnesses, to fussion different information on the same picture. The different attenuations are analyzed and discussed in terms of the charge detection efficiency of the CMOS sensor, measured using Fluorescence X-rays and gamma rays from calibrated sources.
