Abstract

Quantum tomography of cw homodyne detected field quadratures (QHT) is used for investigating quantum states of radiation fields. We apply QHT to the measurement of the transmittance of optical samples illuminated by vacuum squeezed radiation produced by a type-I degenerate OPO operating below threshold. The field reconstructed by QHT contains information about the transmittance of different absorbers illuminated by a very small number of photons.
