Abstract

The invention discloses a cloud layer projection imaging device and a method thereof, relates to the projection imaging device and the method thereof, and realizes the dynamic remote projection imaging on a cloud base by a strong light beam. The device comprises a high power light source, a projection apparatus, a pattern device, a cloud layer detecting apparatus, a mechanical frame and control equipment. The method is as follows: at night, detecting information such as a cloud layer position and the like with the cloud layer detecting apparatus, generating the strong light beam with the high power light source, controlling the projection apparatus in the mechanical frame in real time with the control equipment to project the pattern of the pattern device to the bottom of the cloud layer with high reflectivity within a few kilometers, thus projecting the designated pattern to the bottom of the low-altitude cloud layer so as to play the pattern image for people in the range of scores of square kilometers under the cloud. The method has a series of usages such as beautifying the cloud at night, enhancing atmosphere, widely broadcasting information and advertising outdoors and the like.

Description

technical field [0001] The invention relates to a device and a method for performing optical dynamic projection imaging at the bottom of clouds in the night sky by using a high-power light source to generate strong light beams. Background technique [0002] High-power light source technology continues to develop, and lasers or high-pressure mercury lamps with output power exceeding several kilowatts have appeared. The aerial searchlight with built-in high-power light source can produce strong beams of various colors, and the penetration distance in the air can reach 1-15km. The main application of aerial searchlights is to use the refracted light of strong light to shine on some buildings, squares or scenic spots in big cities to the sky to beautify the night sky, or to illuminate designated areas on the ground at night. [0003] The height of clouds in the sky ranges from a few hundred meters to several kilometers. Some clouds have low heights and high reflectivity. At nig...
