Laser technology applied to cultural performances

"Father of Laser" - Professor Noble, a Nobel Prize winner in physics, discovered the laser and made a very significant contribution to the development of laser application technology in the world. In the industrial, military, medical, mapping, communications, construction, CD, holography, long-range detection, atmospheric pollution, geodesy, molecular spectroscopy, etc. in various high-tech fields are inseparable from the application of laser technology.
As early as 1970, the West German "Bavili" National Opera used lasers in theatrical performances and succeeded, creating a precedent for lasers to enter the art hall. The new technology of laser has been used since the 1960s and applied to cultural performances. Although it has been less than ten years, it has attracted close attention from the art world. The application of lasers in China to the literary performance began in the early 1980s. It was the first time that the Chinese evaluation theater applied the laser to the opening and closing of the drama "Wangfu Monster". At that time, due to the limitations of subjective and objective conditions, 0.75mm was used. The four lasers (red) can be said without exaggeration: "This is the real faint light." However, for the application of laser technology in the field of Chinese cultural performances, it is the "Spark" of "Liaoyuan". Since then, the high-power 20W copper laser has emerged at the opening ceremony of the Seventh National Games. In recent years, large-scale song and dance evenings and large-scale sports games, lasers have become "cooked faces." At the closing ceremony of the Olympic Games in Los Angeles, the high-density laser beam around the stadium was scanned in the night sky, adding a dazzling brilliance to the closing ceremony, which left a deep impression on people; on the National Day of the 35th anniversary of our founding, The first laser show over Tiananmen Square pushed the festive atmosphere to a happy climax. In 2001, the opening ceremony of the Beijing Universiade also used lasers to write a new chapter for the application of new technology in the opening ceremony of the Games.



There are many kinds of professional lighting fixtures in the art performances, each with their own strengths, including spotlights, astigmatism lights, computer lights, roller lights, mushroom lights, celestial lights, phantom lights, gems, moving lights, low beam Lights, aerial scanning lights, outdoor rotating lights, trichromatic fluorescent lights, etc. Laser emitters are unique among these luminaires and have features that cannot be replaced by any other luminaire.



First, the laser is the "light of the finishing touch" and "the finishing touch" is the wonderful thing that everyone can understand. It is impossible to use a laser to complete the lighting and lighting effects from the opening to the closing of the party. This is its The characteristics are determined. Through nearly 20 years of practical experience, we are told that when applying lasers to art halls, we should use them on ideas, and use them less. Do not abuse them. Imagine a colorful party performance. From the beginning to the end, the laser keeps jumping. Flashing, the atmosphere is a bit lively, but the audience can't stand it, and the audience will be disgusted. Therefore, it is advocated to show the artistic charm of laser in key time, key parts, key environment and key atmosphere. For example, 12 years ago, it was also the Lunar New Year of the Lunar New Year. We were on the highest wall of the stadium, letting the "Laser Horse" fly straight from the left side to the right side and turned a big circle. In this way, the prelude of the concert was opened. The "point of the eye" task is also completed part of the program, and then in the program, after screening at the key climax period, a variety of laser graphics, for timely maturity, the audience is very satisfied.



Second, the laser is a "bright light" safflower green leaf support. The positioning of the laser is the starting point, the foil, and the foil in the art field. In some large-scale symphony performances abroad, with the change of the melody of music, the “laser flower basket” above the auditorium and the performance table has a rhythmic flash, which gives the audience an unexpected visual enjoyment. Of course, if the “laser flower basket” appears for a long time. Just messed up the concert. However, the timely image of the laser that is very integrated with the content of the concert is the appropriate setting to add color to the music. At the top of the Diwang Building, the tallest building in Shenzhen, a high-power laser transmitter was assembled. Whenever a strong laser beam was scanned late at night, it was very eye-catching. This is another representative feature of the modern metropolis. The dazzling beam of light swims in the night sky, giving people a warm, straightforward, inspiring and inspiring. At present, there are many cases of abuse of laser phenomenon. When laser application, it is necessary to know the pros and cons of the characteristics and application of the laser, otherwise it will be a help. We have deep experience and lessons in this respect. If the laser application field is in the performance, and a program is not pulled, repeating this is a taboo of art. The laws of art often require us to use less and finer laser applications, to unify the formal content, to adapt to time and space, and to accurately reflect the changing requirements of people, scenes, and time and space. More innovations and innovations should be highlighted when they stand out.



Third, the laser is the "light of fun" in the ocean of children's toys, there is a simple and colorful toy called "Kaleidoscope." Just turn the outer shell of the cylinder, you can see the bottom of the tube through the observation hole, the color pattern changes infinitely, beautiful, so that the children can't put it down. The laser also has this colorful and changeable feature, called it "the kaleidoscope of lasers." Argon-ion lasers, copper lasers, and holmium lasers can be used in performances. They are produced in the US, Shanghai, and Beijing. They are patterned by various imaging methods (including holograms and computer programming, penguins, birds). , running horses, notes and other sports and moving patterns), from the beginning to the end, in more than an hour of performance, the laser pattern is full of colors and changes, fully reflecting the fun of laser in the application of art palace.



In addition to cultural performances, children's playgrounds and advertising production can show the artistic charm of laser. In 2002, in the "Meeting the Window of the World in Shenzhen" New Year's Eve Gala, there was a ballet with acrobatics on the light bulb. The background was a dark blue sky. The actor wore a white dance skirt and a dark green fan-shaped laser beam on the back. Under the circumstance, the actor walked the light bulb to perform the superb, novel and peculiar ballet of the three-person pyramid. This scene reflects the combination of modern laser technology and innovative ballet acrobatics, creating a peculiar and perfect ballet. The art of the painting adds a new artistic realm to the viewer's vision and enjoys the beautiful artistic enjoyment. Therefore, the combination of new science and technology and new artistic creation will inevitably lead to new art works and showcase the infinite artistic creation space of the art palace. When the laser is on the art palace, it is not a simple technique, but an important modeling tool and modeling tool in the art field. The uniqueness of laser is "personality". It is different from lighting. In art creation, we should take its long, avoid short and creative application, make the stage laser art flower bloom, let strong The laser beam of the beam flashes a dazzling light, allowing people to praise it and appreciate it with a new look.
