Abstract:
An optical device includes optical parts including a laser diode element accommodated in a housing. A bimorph-type piezoelectric element is arranged in a vicinity of the laser diode element and has a free end contacting one of the laser diode element, a support member supporting the laser diode element, and the housing. A control circuit controls an operation of the bimorph-type piezoelectric element.
