Compared to Impressionist paintings taken 50 years ago, upon closer inspection of Impressionist paintings in museums, you may notice some strange things: some are losing their bright yellow hue.Taking the dramatic sunset in Edward Munch's masterpiece "The Scream" as an example. The once bright orange yellow parts of the sky have faded to off white.Similarly, in his painting "The Joy of Life", Henr...
LightSolver's new LPU100 system is powered by 100 lasers and can solve the most challenging problems through up to 120100 combinations.This computer was created by Dr. Ruti Ben Shlomi, CEO of LightSolver and Dr. Chen Tradonsky, CTO, a physicist at the Rehowatt Weizmann Institute for Science.It is not suitable for household use because its high computing power exceeds individual needs, but it is su...
Figure: Researchers have created a chip based ring resonator that operates in the ultraviolet and visible light ranges and exhibits record low UV loss. The resonator (small circle in the middle) is displayed as blue light.Researchers have created chip based photonic resonators that can operate in the ultraviolet (UV) and visible regions of the spectrum and exhibit record low UV loss. The ne...
Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...
In today's rapidly developing technological era, structured light laser technology has become an important tool in the fields of 3D measurement and image capture. The core of this technology lies in a magical device called Diffractive Optical Elements (DOE), which can precisely control and shape laser beams, creating various complex light patterns. But what exactly is DOE? How does it work? Let Ho...
