    "abstract": "A method for measuring the transmittivity of optical samples by using\nsqueezed--vacuum radiation is illustrated. A squeezed vacuum field generated by\na below--threshold optical parametric oscillator is propagated through a\nnondispersive medium and detected by a homodyne apparatus. The variance of the\ndetected quadrature is used for measuring the transmittivity. With this method\nit is drastically reduced the number of photons passing through the sample\nduring the measurement interval. The results of some tests are reported.",
