ABSTRACT:
Optical cables, which are connected to a light receiving section and a light transmitting section, respectively, are provided to be opposite to each other in three-axis directions to be freely movable and adjustable to image forming lenses of a receiving optical system and a transmitting optical system, respectively. The optical fiber is driven based on light intensity of receiving light to be three-dimensionally moved and adjusted so as to optically combined with the image forming lens, and the optical fiber is driven based on a light angle of the receiving light and aberration to be three-dimensionally moved and adjusted so as to optically combined with the image forming lens.
