    "abstract": "We present a homodyne detection scheme to verify Bell\u0027s inequality on\ncorrelated optical beams at the output of a nondegenerate parametric amplifier.\nOur approach is based on tomographic measurement of the joint detection\nprobabilities, which allows high quantum efficiency at detectors. A\nself-homodyne scheme is suggested to simplify the experimental set-up.",
