The principle of the laser lamp used in the above-mentioned entertainment occasions is that the laser is reflected on the stepping motor or high-speed vibrating mirror through the optical lens, and then the stepping motor/vibrating mirror generates up, down, left and right figures by dithering the X-axis /Y-axis at high speed, and creates complex figures/figures/animations/sectors/points with the help of delayed light induction of human eyes and TTL adjustment inside the laser.
