Abstract
An optical device including a reflecting device, a focusing device and a processing device for realizing image data of a target object is disclosed. The focusing device is located within an enclosed area surrounded by a reflective light track so that the two light paths respectively from the target object to the focusing device through the reflecting device, and from the focusing device to the processing device are overlapped. By this way, the size of the optical device contributed by the distance between the reflective device and the processing device is reduced.
