Laser Safety Plane: Below This Line is Okay to Scan

Laser beams form a set of fan-shaped horizontal planes in the space, but all beams strictly remain above a height of 3000mm from the floor, never sweeping across anyone's head height. Therefore, from the perspective of people on the dance floor, the laser appears as a layer of glowing net unfolding above their heads, which they can look up at but not touch. The laser emitters are mounted high on the side walls, with their angles fixed by mechanical stops. The beams appear as clear green or white fine lines in thin fog, interweaving into geometric patterns. The image is an upward view from the dance floor, with people below and light above. Avoid: beams sweeping to people's height, emitters placed low, beams drawn thick and diffuse, people reaching out to touch the beams.

雷射光束在空間裡形成一組扇形的水平面,但所有光束都嚴格保持在地坪以上 3000mm 的高度之上,絕不掃過任何人的頭部高度。因此從舞池裡的人的視角看,雷射是在頭頂上方展開的一層發光的網,可以抬頭看但碰不到。雷射的發射器架在側牆的高處,角度被機械限位固定。光束在薄霧中呈現清晰的綠色或白色細線,交織成幾何圖案。畫面從舞池仰視,人在下方,光在上方。避免:光束掃到人的高度、發射器設在低處、光束畫得粗散、人伸手去碰光束。
