Holographic display technology provides the ultimate solution for true 3D display, with enormous potential in augmented reality and virtual reality. However, the color and viewing angle of holographic 3D displays mainly depend on the wavelength of the laser and the pixel size of the current spatial light modulator. The inevitable color difference and narrow viewing angle in conventional systems se...
Latest news: Rheinmetall and European Missile Group Germany plan to establish a joint venture to develop shipborne laser weapons.The cooperation between the two companies in the field of military laser technology has been ongoing for several years. In 2022 and 2023, under the framework of the High Energy Marine Laser Demonstration Working Group (ARGE), the jointly developed laser was successfully ...
Recently, BLM GROUP USA, a leading manufacturer of laser tube and sheet metal processing equipment, announced that its North American headquarters in Novi, Michigan has officially started construction, with plans to add 65000 square feet of modern facilities. It is expected to be completed and put into use in the third quarter of 2025.The specific investment amount for this expansion has not been ...
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...
Tunoptix, a developer of computational meta-optics, based in Seattle, WA, has made what it calls “a breakthrough in mobile-scale spectral imaging”. The company’s latest meta-optical platform captures high-fidelity spectral signatures across the visible-to-NIR spectrum in a compact form factor smaller than 1 cm3, consuming less than 500 mW, and operating at real-time frame rates.Tunoptix’s ultra-c...
