Light deflection device, image projector, laser head lamp, and mobile object |
| abstract |
A light deflection device includes a reflector; a drive beam supporting the reflector such that the reflector is movable; a supporting section supporting the drive beam; and a piezoelectric drive circuit disposed on the drive beam. The light deflection device further includes circuitry configured to output a first drive-voltage waveform and a second drive-voltage waveform to the piezoelectric drive circuit. The first drive-voltage waveform has a period of a positive slope within one cycle, the period of the positive slope includes a period of a first slope and a period of a second slope different from the first slope. The second drive-voltage waveform has a period of a negative slope within one cycle, and the period of the negative slope includes a period of a third slope and a period of a fourth slope different from the third slope. |
