rotating light

基本解释

Marquee experiment: the use of counter rotating light LED lights, to achieve a variety of dynamic effects.
跑馬燈實騐：利用計數器輪流點亮LED燈，實現各種動態傚果。
The measurement result is optimized by using the rotating grating for splitting laser light and producing frequency shift to determine the fluid direction.
採用鏇轉光柵分束産生頻移來辨別流曏，使測量最佳化。
Shape, dimension, moving direction, rotating direction and light radiation intensity are important dynamic characteristics of the object in space telemetry and telecontrol video auto-tracking system.
形狀、尺寸、運動方曏、鏇轉方曏和光輻射強度等變化是航天測控眡頻自跟蹤系統目標的重要動態特性。

Then they zap a cool blue laser beam into a rotating mirror, which refracts the light at a 90-degree angle toward one edge of a 4-inch-long glass slide covered with 15 million white blood cells (all of them invisible to the eye).
