1. An optical device, comprising:
a light receiving element for detecting light reflected and transmitted from a subject;
a voltage part for providing a first bias voltage or a second bias voltage to the light receiving element; and
a controller for controlling the voltage part so that the second bias voltage provided from the voltage part is synchronized with a light output of a light emitting part to be provided to the light receiving element,
wherein the second bias voltage comprises a voltage in which a sub bias voltage is added to the first bias voltage.
