Zusammenfassung:The general concept of generalized quantum measurements with minimal distortion of initial information, which was introduced in our earlier publication [1] is applied to the problem of continuous quantum variables measurement. The qualitative features of such measurements are revealed and compared with a standard completely dequantizing measurement, which is described by the corresponding positive-definite operator-valued measure.
