Abstract
A rising time period UA is a predetermined first time period. As exemplified by a first non-irradiation time period NA1 or a second non-irradiation time period NA2, in a partial time period of the predetermined first time period, a movable reflection unit (120) is not irradiated with beams B and a vertical drive signal SA has a predetermined first slope. As exemplified by an irradiation time period MA, in a different partial time period of the predetermined first time period, the movable reflection unit (120) is irradiated with the beams B such that the vertical drive signal SA has a second slope different from the first slope.
Claims9
An optical device comprising:
- a signal generation unit which generates a drive signal for driving a movable reflection unit which reflects beams emitted from a light-emitting element in a predetermined direction,
- wherein a predetermined first time period in which the drive signal transitions from one of a maximum value and a minimum value of the drive signal to the other includes a time period in which the movable reflection unit is not irradiated with beams and the drive signal has a predetermined first slope, and a time period in which the movable reflection unit is irradiated with the beams and the drive signal has a second slope different from the first slope.
