摘要：

A method for measuring the transmittivity of optical samples by using squeezed vacuum radiation is illustrated. A squeezed vacuum field generated by a below-threshold optical parametric oscillator is propagated through a non-dispersive medium and detected by a homodyne apparatus. The variance of the detected quadrature is used for measuring the transmittivity. With this method the number of photons passing through the sample during the measurement interval is drastically reduced. The results of some tests are reported.
