The working principle of the music fountain is that each galvanometer scanner is equipped with a total reflection mirror, and the rotation axes of the total reflection mirrors on the two galvanometer scanners are perpendicular to each other. The scanning deflection angle of the galvanometer and the scanning frequency of the light spot are strictly controlled by the computer. The high-brightness laser beam hits the total reflection mirror of the galvanometer scanner, and the two total reflection mirrors perform a two-dimensional scanning motion under the control of the computer signal. and text.
The water mist and water droplets sprayed by the nozzles form an ever-changing water curtain in the continuous rolling motion of the space. The laser beam continuously scans back and forth on the water curtain, and the light spots are constantly reflected (scattered) in motion, displaying a specific pattern. As long as the scanning time of the light spot is controlled to be less than 1/10 of a second, using people's visual persistence effect and the reflection and refraction of water droplets under the laser beam, there will be some depth-sensing graphics or images in the three-dimensional water curtain space. Word. Graphical programming and man-machine intercom can be easily carried out on the computer. As long as the frequency of light spot scanning is changed, the graphics on the water curtain can also flicker.
