    "abstract": "We present a new scheme to detect and visualize oscillations of a single\nquantum system in real time. The scheme is based upon a sequence of very weak\ngeneralized measurements, distinguished by their low disturbance and low\ninformation gain. Accumulating the information from the single measurements by\nmeans of an appropriate Bayesian Estimator, the actual oscillations can be\nmonitored nevertheless with high accuracy and low disturbance. For this purpose\nonly the minimum and the maximum expected oscillation frequency need to be\nknown. The accumulation of information is based on a general derivation of the\noptimal estimator of the expectation value of a hermitian observable for a\nsequence of measurements. At any time it takes into account all the preceding\nmeasurement results.",
