摘要： A distributed Bragg reflection (DBR) semiconductor laser is controlled in an image projecting apparatus. The image projecting apparatus includes the DBR semiconductor laser which is provided with a phase region and a DBR region, a light wavelength converting device for converting fundamental-wave light emitted from the DBR semiconductor laser into second harmonic wave light, an optical deflector for scanning the second harmonic wave in a one-dimensional or two-dimensional manner, and a modulating portion for modulating the DBR semiconductor laser based on an image signal. In the control method, a coefficient calculating step and a wavelength adjusting step are performed within a non-drawing time during which a drawing signal, which corresponds to the image signal, is absent. In the coefficient calculating step, 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 is calculated. In the wavelength adjusting step, the DBR current injected into the DBR region and the phase current injected into the phase region are changed based on the relationship such that the second harmonic wave light is adjusted.

摘要： An optical deflector comprises a vibration system and a driver. The vibration system includes a first oscillatory moving element having a reflecting surface, a second oscillatory moving element, and a support. The first and second oscillatory moving elements are resiliently supported respectively by first and second torsion springs to be able to torsionally vibrate about an oscillation axis with respect to the second oscillatory moving element and to the support.
