The CES exhibition was held in Las Vegas from January 9th to 12th, US time. As a 50-year-old international consumer electronics exhibition, too many "firsts" in the history of human science and technology were born here. Every year at CES, manufacturers will display their latest products and technological achievements. This year, artificial intelligence is still the hottest topic, and in the field of commercial display equipment, holographic projection has brought no small surprises to the audience.
Holographic fan can display suspended images
Holographic projection technology (front-projected holographic display), also known as virtual imaging technology, is a technology that uses the principles of interference and diffraction to record and reproduce real three-dimensional images of objects. In recent years, the commercial potential of holographic projection has gradually emerged, but since the real holographic projection still has technical barriers, it is still a long time before commercial use. But at the CES exhibition, we found a product from Shenzhen, China, which looks exactly like a fan, so many people call it "LED fan" or "holographic fan."
The structure of the "holographic fan" is not complicated. Two fan blades are embedded with LEDs. When the "fan" rotates, a 3D image is finally formed under the principle of persistence of human vision, resulting in objects hanging in the air. The illusion of stopping. With this device called "holographic advertising machine", people can see 3D floating images without naked eyes.
