rotating light

基本解釋

Marquee experiment: the use of counter rotating light LED lights, to achieve a variety of dynamic effects.
跑馬燈實驗：利用計數(shù)器輪流點亮LED燈，實現(xiàn)各種動態(tài)效果。
The measurement result is optimized by using the rotating grating for splitting laser light and producing frequency shift to determine the fluid direction.
采用旋轉光柵分束產(chǎn)生頻移來辨別流向，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、運動方向、旋轉方向和光輻射強度等變化是航天測控視頻自跟蹤系統(tǒng)目標的重要動態(tài)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).
