On December 27th, researchers from the University of Michigan in the United States developed a new type of incandescent light bulb. With the precise design of the filament itself, this light bulb is capable of emitting elliptically polarized light (twisted light) and is 100 times brighter than previous methods. This new design helps to enhance people’s understanding of fundamental physics and paves the way for the application of robot vision systems and other cutting-edge technologies.
