We have performed optoelectronic correlation measurements in a CdTe po
lycristalline photoconductive switch for two wavelengths 810nm and 532
nm, like the method described by Shu [1]. The aim of this study is to
calculate carrier lifetime and mobility of this material thanks to ult
rafast electrical pulse generation and detection. We present experimen
tal conditions and basic equations used to determin photoconductive fe
atures.
