    "abstract": "We present a new indirect method to measure the quantum state of a single\nmode of the electromagnetic field in a cavity. Our proposal combines the idea\nof (endoscopic) probing and that of tomography in the sense that the signal\nfield is coupled via a quantum-non-demolition Hamiltonian to a meter field on\nwhich then quantum state tomography is performed using balanced homodyne\ndetection. This technique provides full information about the signal state. We\nalso discuss the influence of the measurement of the meter on the signal field.",
