The CES exhibition was hel₹≥€d in Las Vegas from January 9th t≈≠o 12th, US time. As a 50-year-old ≠$ international consumer electronics exhibition•♥Ω, too many "firsts" in the history∑& of human science and→&π technology were born here. E®φvery year at CES, manufacturers☆> will display their latest products an¥€d technological achievements. This y★₩✔ear, artificial intelli↔↑ gence is still the hottest topic, and in t≤¥→↓he field of commercial displa™αy equipment, holographic projecti•₹on has brought no small surprΩ$₩Ωises to the audience.
Holographic fan can display suspended images
Holographic projection technology (fro∞↓nt-projected holographic display), als o known as virtual imaging tec®¥hnology, is a technology that u<∞ses the principles of interf>↓✘erence and diffraction to r≥'•ecord and reproduce real thλree-dimensional images of objects©&"". In recent years, the commercial potential of ho§φ÷©lographic projection ha<♠s gradually emerged, but since 䙧÷the real holographic projection still has techni↑&¶™cal barriers, it is still a long tim<¶e before commercial us↓∏e. But at the CES exhibition,≈♥§ we found a product from Sλ§henzhen, China, which looks e§λ±xactly like a fan, so many pe↑♦ople call it "LED fan" or "ho£"lographic fan."
The structure of the "holographic™π fan" is not complicatedγ₽. Two fan blades are embedded wit'Ωh LEDs. When the "fan" rotates, a 3€γD image is finally formed under the princip✔φ→₩le of persistence of humanφ☆δ vision, resulting in objects hanging in•♠★∏ the air. The illusion of stoppi&₹✘εng. With this device called &qu"≈α∏ot;holographic advert÷↓ising machine", p≤•'eople can see 3D floating i✘ שmages without naked eyes.
