cloud imaging solutions:
- Technical principle: Utilize ALPD laser display technology. A light source with a specific brightness is projected onto the cloud layer. Relying on the reflectivity of the clouds, imaging on the cloud is achieved through a lens. Different cloud heights and types affect the imaging. For example, high - clouds (h>6000m) have a reflectivity of 25%, middle - clouds (2500m<h<6000m) have a reflectivity of 50%, and low - clouds (h<2500m) have a reflectivity of 65%.
- Equipment parameters: The self - developed laser "cloud - projecting" equipment has dimensions of 1110×1044×612mm, weighs 100Kg, has a brightness of 100,000lm, a projection distance of 30 - 3000m, a projection angle of 35° - 90°, a beam angle of 1° - 2°, projection colors including R, G, B, and Y, a power supply voltage of 200 - 240V AC, and a maximum current of 16A.
- Application cases
- 2022 Winter Olympics: For the first time globally, laser was used to "write on the clouds", writing the words "One World, One Family". This technology was also applied in the opening ceremony and other segments.
- Bing Dwen Dwen display: The tallest and largest Bing Dwen Dwen image on the Internet was created in the night sky of Shenzhen.
- Local culture: It helped promote Chaozhou Gongfu Tea, showing the phrase "Beautiful mountains, beautiful waters, and great Gongfu". It also enabled the collision between Jining culture and high - tech. In addition, it was applied in Shenzhen light shows and the conscription promotion of Shenzhen University.
- Project features: The on - site implementation is simple, and it can be powered by external municipal electricity. It can be lit for a long time, is green, environmentally friendly, and pollution - free. It can continue to be used in rainy weather. Moreover, gobo sheets can be customized according to requirements to present different patterns and color effects.
