Abstract
The AO system calibration is usually done with a dedicated setup during daytime. Here we present results of two alternative techniques as the synthetic and the on-sky interaction matrix calibration. In both cases we created matrices controlling 400 modes of the LBT-FLAO system. We present here the performances reached on-sky at LBT compared with those obtained with the standard calibration. The described techniques allow calibrating the AO system without any dedicated hardware. This is particularly attractive for systems that require complex calibration setup such as those with a convex adaptive secondary like the MMT and the planned VLT AOF.
