Abstract
There have been problems that a capturing device requires an optical source having a large power output, and a scanning operation and a capturing operation must be alternately performed by the respective devices. A capturing device is provided with an optical receiver which receives a beam from outside as a reception beam, a reception beam capturing unit which performs a capturing operation by which the reception beam is introduced to the optical receiver, an optical transmitter which generates a transmission beam transmitted to the outside, a transmission beam scanning unit which performs a scanning operation of the transmission beams, and an optical circulator wherein the incidence of the reception beam and the exit of the transmission beam are performed at the same terminal.
