可视化新方法直观呈现“特勒尔效应”

Group 1 - A research team from Vienna University of Technology and University of Vienna has visualized the "Terrell Effect" for the first time, which describes how fast-moving objects appear to rotate due to the varying light travel times from different parts of the object to the observer [1][2] - The study published in the latest issue of "Communications Physics" highlights that when a rocket moves at 90% of the speed of light, its length contracts by 2.3 times, demonstrating the phenomenon of length contraction known as Lorentz contraction [1] - The research team utilized a "time-space slow down" technique by using femtosecond laser pulses and ultra-precise time-gated cameras to effectively reduce the speed of light to 2 meters per second, allowing them to capture optical distortions of a cube and a sphere [2] Group 2 - The visualization of the "Terrell Effect" not only aids in understanding complex physical theories but also represents a successful intersection of art and science, showcasing the collaboration between artists and scientists [2] - The study indicates that the cube appears to rotate in the images captured, with its front edge becoming prominent while the back edge extends like a cape, while the sphere maintains its symmetrical shape but shows uneven light distribution on its surface [2]
