In this paper, we present a theoretical study of the quantum-nondemolition properties of a scheme that uses a Kerr medium in a double-ended cavity with both the signal and the probe inputs being coherent fields incident from the two sides. We find that with a suitable choice of parameters this system satisfies almost perfectly the criteria for quantum-nondemolition measurements.
