New Tech Uses Twisted Light to Reveal Hidden Images
Imagine a chip so thin it looks like nothing—until you shine twisted light on it. Scientists have developed a metasurface that can hide and reveal two entirely different images depending on the light’s polarization. Using carefully arranged nano-structures, this technology doesn’t just trick the eye—it opens doors to next-gen encryption, biosensing, and quantum tech. From [...]
