Abstract
An optical device provided by the present invention can comprise: a light transmitting unit for generating a first beam for photographing a certain area; a light receiving unit for sensing a second beam returning from the certain area; a light separating unit for distinguishing and transmitting the first beam from the second beam; and a detection unit including a micro electro-mechanical system mirror (MEMS mirror) for transmitting the first beam by changing an optical axis up to a first steering angle, and for receiving the second beam.
