摘要：When a light intensity upon a perturbation is detected, an error

calculation/correction unit () in a control unit () corrects and updates the above-describedinitial manipulated variables based on perturbation manipulated variables and

manipulated variables, i.e., operation manipulated variables to obtain the maximum lightintensity from the light intensity value at each perturbation manipulated variable, therebyadjusting the tilt angle of a mirror. More specifically, assuming that the time series dataof an acquired output light intensity can be approximated to a cosine function, the errorcalculation/correction unit () calculates a phase difference θ between the cosine functionand a sine or cosine function used to set x- and y-axis perturbation patterns for a circulartrajectory perturbation. Manipulated variables at coordinates defined by the phasedifference θ and polar coordinates of a radius voltage to perturb the mirror arecalculated. Voltage values at coordinates defined by a function for setting the drivingvoltages of the mirror () are calculated and set as the driving voltages for one outputport.
