Neutron imaging is a very powerful technique for nondestructive testing; it allows obtaining image of the internal structure of objects in 2D or 3D mode.
During the last years, attempts have been made to implement and to develop a neutron tomography system at the Nuclear Research Center of Birine. At this end a new Peltier-Cooled CCD (16 bit) has been installed instead the old CCD camera (8 bit) and a turntable has been designed.
The aim of this work is to calculate the spatial resolution of a CCD camera and a scintillator based neutron imaging system by the measurement of the MTF which is obtained by a slanted edged image. On the other hand, we will give some results obtained through the characterization of the image detector such as the variation of the gray level as a function of exposure time and the effect of the cooling of the CCD camera on the noise signal.
