MTF measurements of a frame transfer CCD operating in TDI mode

A simulation set-up, radiometrically representative of a high resolution Earth observation condition from a geosynchronous spinning spacecraft has been built. This simulation set-up is used to verify the performance of a commercially matrix CCD (THOMSON-CSF type TH7864) when operating in time delay and integration (ThI) mode. MTF measurements results of this TDI operating CCD are presented in this paper and are compared with MTF values of the same CCD operating in a conventional staring mode
