摘要： A DBR semiconductor laser is controlled in an image projecting apparatus, which includes the DBR laser having a phase and DBR region, a light wavelength converting device for converting fundamental-wave light emitted from the DBR laser into second harmonic wave light, an optical deflector for scanning the second harmonic wave in a one or two-dimensional manner, and a modulating portion for modulating the DBR laser. Coefficient calculating and wavelength adjusting steps are performed within a non-drawing time. The coefficient calculating step calculates at least one coefficient in a relationship between a DBR current to be injected into the DBR region and a phase current to be injected into the phase region for continuously shifting the wavelength of the fundamental-wave light. The wavelength adjusting step changes DBR current injected into the DBR region and phase current injected into the phase region based on the relationship.

摘要： The optical deflector includes a deflector, a vibration detector, a driving signal generator, a modulation timing signal generator, and a deflection detector. The deflector has a vibrational system having a movable body with a light deflecting member, and deflects light from a light source by the movable body. The vibration detector detects the vibration condition of the vibrational system of the deflector. The driving signal generator generates a driving signal for driving the vibrational system of the deflector. The modulation timing signal generator generates a modulation timing signal as the reference time for regulating the amount of light from the light source. The deflection detector detects the deflection condition of light deflected by the deflector. The driving signal generator generates the driving signal based on information of the vibration condition detected by the vibration detector, and the modulation timing signal generator generates the modulation timing signal based on information of the deflection condition detected by the deflection detector.

摘要： An image forming apparatus detects a oscillating state of a oscillation system with a oscillation detector and controls oscillation of the oscillation system such that the oscillation system oscillates a reflective member in a balanced steady state by adjusting a drive force of a drive unit with one or more drive control parameter values on the basis of the detection result obtained by the oscillation detector. When the balanced steady state is detected, the drive control parameter values are stored and are used when an exposure unit is reactivated.
