Abstract
We analyse schemes for linear measurements of the photon number of a l ight beam and address how much information it is possible to extract f rom a quantum detector in single or repeated measurements, how much in formation is destroyed in non-ideal situations, and how much backactio n is imposed for the extracted information.
