This paper is devoted to the presentation of a new technique of characterization of the intra-pixel sensitivity variations (IPSVs) of astronomical detectors. The IPSV is the spatial variation of the pixel response function (PRF). In the case of under-sampled instruments for high quality imaging and accurate photometry, IPSV can contribute to the instrument global error and it should be considered...
We studied the electromechanical properties of PMN-PT and PZN-PT single crystal plates poled along [001] with thickness t ranging from 800 down to 70 mum. In the case of the tetragonal single domain state (IT), the properties of the thickness mode remain stable down to 250 mum. Below 250 mum, an instability of the polarization is shown. The plates exhibit regions where polarization lies in the plane...
