A laser beam is condensed in a close position to a target object in underwater so as to generate an air bubble or plasma. The target object is efficiently destroyed by a shock by the air bubble or the plasma.

Underwater object destruction system and underwater object destruction method

A solid obstacle is removed with a high-power laser beam to establish a transmission path for a spatial laser communication. When a space in which the laser beam is transmitted is blocked off by the solid obstacle, the spatial laser communication cannot be carried out.

Laser communication system and laser communication method

An optical test apparatus includes a three-dimensional dome, light sources and a control unit. The three-dimensional dome covers a field of view of an image acquisition device. The image acquisition device is a test target device. The light sources are dispersedly arranged on the three-dimensional dome and generate a predetermined image on the three-dimensional dome. The first control unit controls the light sources.

Optical test apparatus

An image obtaining apparatus has a swing-type optical system, an optical dome and a correction optical system. The swing-type optical system is configured to adjust a photographing direction based on a swinging operation. The correction optical system corrects transmitted light beams through the optical dome to parallel light beams parallel to the photographing direction.
