    摘要： An S/N calculation circuit 12 to calculate the S/N ratio of a received signal, and an S/N comparison circuit 13 to compare the S/N calculated by the S/N calculation circuit 12 with a threshold Th are disposed, and a parameter setting circuit 14 controls the radiation state of a beam radiated from a transmission optical system 5 according to the result of the comparison performed by the S/N comparison circuit 13. As a result, even if the state of the propagation environment gets worse, degradation in the communication quality can be prevented and communicative stabilization can be achieved.

    摘要： An optical antenna device (1) includes: an optical lens system (13) for focusing a laser beam; an optical-system holding member (10) for holding an outer peripheral edge of the optical lens system (13); an optical connection member (20) placed on a rear focal plane of the optical lens system (13); first shaft portions (15A, 15C) extending from an end of the optical-system holding member (10) toward the optical connection member (20) and each having a first linear expansion coefficient; and second shaft portions (16A, 16C) extending from an end portion of the optical connection member (20) toward the optical-system holding member (10). The second shaft portions (16A, 16C) each have a second linear expansion coefficient different from the first linear expansion coefficient. The first shaft portions (15A, 15C) and the second shaft portions (16A, 16C) are respectively fixed to each other at a predetermined fixing position between the optical-system holding member (10) and the optical connection member (20).

    摘要： A system controller 16 determines whether the quality of either a distance image or a light intensity image satisfies reference quality, and, when the quality of either the distance image or the light intensity image dos not satisfy the reference quality, outputs a speed change command to lower a speed, an altitude change command to change a submarine altitude (depth), or the like to a navigation control unit 2, thereby changing a physical relative relation between a measurement plane 3 and a device in question. As an alternative, the system controller changes a beam scanning rate f, a beam divergence θ, or the like within limits at which the amount of variation in a spatial resolution does not exceed a permissible amount.
