JSM水幕激光
 JSM Laser Water Curtain

一、绪论
　　 激光，光色纯正，能量集中，已成为新型的民用发光体。利用现代高科技光学技术，能在烟雾、水幕等介质上形成色彩鲜艳、表现独特的图形、文字、动画。激光表演系统就是采用这种高能量光源和高科技光学技术，由计算机控制，在定制的介质上表现独特的效果。激光表演技术是一种集声、光、电、机与一体的技术；而激光作为一种表演系统。能体现出主办者的艺术造诣不口艺术修养。
　　 激光可以直接扫描或通过棱镜、转镜、光栅等光学设备的光学原理工作。其工作方式的不同，可产生不同的效果，营造出多姿多彩的现场气氛。如：光束光芒、海涛波浪、时光隧道、万丈光芒、秋景怡人、动画图文、音乐效果。
　　 到目前为止，国内还没有几家能把音乐和激光表演内容结合起来。我们能够将它们完全默契地结合一体。使观众能用眼睛来看激光，听音乐。将音乐的旋律演绎的淋漓尽致。事实证明，两者结合在一起效果是非凡的。
　　 激光音乐喷泉的图象介质是水——水幕、特色喷泉，其特点是突出水的流动质感，激光表演是把点、线、面、立体多方位结合，把空间效果发挥的淋漓尽致。音乐、喷泉、激光三者有机结合在一起．创造美妙景象，震撼人的视觉感官。

二、系统特点
1．技术先进
　　·解决了激光显示系统的稳定性。可以连续长时间的使用而无任何问题。
　　·操作简单可靠，交钥匙式工程技术，激光设备免维护。使非激光专业人士也能轻松操作。
　　·多光笔的扫描及控制技术。可以在表达复杂大场面、大空间时显示出气势辉弘的效果。
　　·由于单束激光能量强，在水幕上能够非常突出地显示文字、图案等。这是其他手段所不能比拟的。
　　·激光表演系统是世界先进的大型表演系统，它融合了激光、计算机控制绘图、精密光学机械等先进的科学技术。创造出宏伟壮观魅力无限的图纹图像、神奇莫测的光芒。
2．气势恢弘
　　·该系统是一种具有动感的户外广告媒体。
　　·它比目前流行的大型电子显示屏的面积大许多倍。数百米外清晰可见，气势恢弘。
3．色彩绚丽
　　“激光水幕”采用国际上最先进的激光扫描成像系统、激光投影系统，通过光束扫描和光功率的变化，能得到很高的亮度和绚丽的色彩，具有丰富的表现能力。
4．图象清晰
　　“激光水幕” 由于水幕均匀、致密、透明，加上成像投影技术先进，图文功能很强，使得整个投影画面具有立体、清晰、逼真的效果。
5．形式新颖
　　电影、电视、电子荧屏、霓虹灯等，可以说司空见惯了，已很难引起人们的注意。但“激光水幕”其表现方式与众不同。由于水幕面积大，气势恢弘，加上屏幕透明，图象清晰，色彩绚丽，放映时周围的水雾更增添几分神秘色彩。而且表演主要在夜间进行，造就海市蜃楼之感。

1. Introduction
　　The laser has pure color and centralized energy, and has become a new type civil luminous body. Taking modern high optical technique, it can form colorful and unique picture, character and cartoon on medium such as smoke and water curt,tin. The laser performance system is to adopt such high energy light source and high Optical technique to make unique effect which is controlled by the computer on the custonaized. It is a technique which incorporates sound, light, electricity and machine into a whole. As a performance system, the laser can embody artistic attainments and accomp lishments of the sponsor.
　　The laser can be directly scanned or operate depending on optical principle of optical devices such as prism, tilting mirror or optical grating. Depending on different operating style, it can produce different effects and form diversified field atmosphere such as light beams, oceans and waves, time tunnel, shine with boundless radiance, autumn sceneries, animated pictures and musical effects.
　　Up to now, fewer manu facturers can combine music with laser performance in the country.
　　We can now combine them into a whole organically and let audiences to watch laser and hear music, to bring the musical melody into full play. In fact, the combination of the both has an extraordinary effect.
　　The image medium of the laser music fountain is the water-water curtain and featured fountain. It has feature to display the flow qunlity of the water, to combine dot, line, face and cube into a whole, and to bring the spatial effect into full laser can create wonderful scenes to shake people,s visual organ.

2. Characteristics of the Systena
1. Advanced Technique
. It solves the stability of the laser display system and can operate for continuous long time without any problems. Simple and reliable operation, turnkey engineering technique and maintenance-free laser devices. Non--professional persons can also operate laser devices freely.

. Multiple light--pen scanning and control technique to display grand and gorgeous effect when showing large complicated scene and space.
.As single beam of the laser has strong energy, it can strongly focus wards and patterns on the water curtain what other measures couldn,t match.
.The laser performance system is an advanced largescale performance system in the world. It merges advanced technique such as laser, plotting controlled by the con,puter, precision optical machinery ect. to generate grand marvelous images and mysterious rays of light.
2. Grand Momentum
.The system is an outdoor advertise ment media with moving effect.
.It has an area much more larger than that of current largescale electronic display screen, With its grand momentum, it can be viewed clearly several hundreds of meters afar.
3. Gorgeous Colors
"Laser Water Curtain" adopts the most advanced laser scanning and imaging system and the laser projection system in the world Through scanning of light beam and change of light power, it can obtain very high brightness and gorgeous colors and rich expressing ability.
4. Distinct Images
As "Laser Water Curtain" has even, dense and transparent ligatures plus advanced imaging projection technique and stronger picture process function, it can make the whole projection have stereo, clear and vivid effects.
5. Novel Form
It is a common sight for movie, TV program, electronic screen and peon lamp etc. which are hardly to arise people’s attention. However "Laser Water Curtain" has the performance out of ordinary, is the water curtain has large area, grand momentum plus transparent screen, distinct pictures, gorgeous and some mysterious color from water mist around when the movie is played at night, it gives people the feeling of mirage as well as strong shock and
attractive power.
