There have been problems that a capturing device requires a light 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 a light 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 light receiver, a light transmitter which generates a transmission beam transmitted to the outside, a transmission beam scanning unit which performs a scanning operation using 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. |
