Submerged laser television and submerged laser visual recognizer

An underwater laser visualization device which radiates laser pulses to a visualized object so as to produce an image of the visualized object based on reflection light of the laser pulses, said underwater laser visualization device characterized by comprising:

• a laser transmission and light receiving device for outputting the laser pulses and for receiving the reflection light to produce the image of the visualized object;
• a light course setting device for setting a course of the laser pulses, output from the laser transmission and light receiving device, to coincide with a first direction or a second direction perpendicular to the first direction, and for setting a course of the reflection light, incoming from the first direction or the second direction, to coincide with a receiving light axis of the laser transmission and light receiving device;
• a pressure-proof vessel for storing the light course setting device and the laser transmission and light receiving device, and for providing first and second light transmission windows for transmitting the laser pulses and the corresponding reflection light, courses of which are set by the light course setting device;
• and
• mounting means, fixed by a support body, for supporting the pressure-proof vessel to have a capability of free rotation while using the first direction as a direction of a rotation axis.
