ABSTRACT:
A laser optical device, having: a laser light emitting section to emit laser signal light modulated by information; a laser light receiving section to receive the laser signal light emitted from the laser light emitting section; a light condensing optical unit to conduct the laser signal light emitted from the laser light emitting section to the laser light receiving section; an actuator to move the light condensing optical unit; a light intensity detecting section to detect an intensity of the laser signal light conducted to the laser light receiving section; and a control section to control drive of the actuator so as to align the laser signal light conducted by the light condensing optical unit to the laser light receiving section; wherein the control section drives the actuator in a predetermined period which synchronizes with a predetermined signal included in the laser signal light.
