Abstract
An underwater laser television, which radiates laser pulses, output from a laser oscillator, to a visualized object under water and detects reflection light of the laser pulses to display an image of the visualized object, is constructed by a main body which is located under water to have a capability of free movement and to resist against the water pressure and which provides a light transmission portion for transmitting the laser pulses and reflection light, the laser oscillator arranged inside of the main body, radiation and light receiving means, arranged in the main body, which radiates the laser pulses toward the visualized object and detects the reflection light to produce video signals of the visualized object, and display means, arranged in the main body, which displays an image of the visualized object based on the video signals.
