Abstract
A light emitting device includes a light source that emits an optical beam in response to a control signal, an optical deflector that changes a direction of the optical beam in response to a driving voltage, and a control circuit that controls a timing of emission of the optical beam and the direction of the optical beam. The optical deflector is configured to change the direction of the optical beam along a first direction and a second direction different from the first direction and a rate of change in the direction of the optical beam along the first direction is lower than a rate of change in the direction of the optical beam along the second direction.
