Not long ago, an alternative concert was held at a cultural center in Shanghai. The singer was a virtual song artist, Luo Tianyi, who sang songs based on holography, AR, VR, and motion capture techniques.
The holographic projection technology behind "Luotianyi" deserves attention. Holographic projection technology is a technique that uses the principle of interference and diffraction to record and reproduce three-dimensional images of objects. It can not only produce three-dimensional illusions of the air, but also can make phantoms interact with performers and create stunning effects.
The U.S. military conducted a holographic projection technology experiment in Somalia. On the day of the test, there was a maddening wind and darkness. An image of Jesus’ suffering appeared in the air filled with sand and fog. Then there was a sound: "Let down and return to Allah!" At that time, the US troops stationed in Somalia. It was terrified. One soldier said: "I am not the most religious person, but when I see the image of God appearing in the air, my mind is blank and I cannot speak or think. I can't help falling down and burst into tears."
In June 2014, a California-based company developed a three-dimensional holographic projector with the size of a pill, which can precisely control the brightness, color, and angle of each beam. Imagine that in the future battlefield, if such a projector is sent to combat officers and soldiers, one party obtains information about the enemy's family and then puts their loved one's image in front of them. When the officers and men saw the picture of the family sending out “children, we need peace!†and “Mum needs you to come back alive!â€, what kind of scenes will appear on the battlefield? This kind of psychological warfare with high-tech implementation needs to be highly valued.
