In a recent study published in the journal AIP Advances, researchers used molecular and elemental spectroscopy techniques such as laser induced breakdown spectroscopy (LIBS), Raman spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy to characterize mines in ancient Egypt.In this study, researchers examined various gemstones that can be traced back to the era of the pharaohs. The team...
The high-end laser cutting machine developed and produced by Dongying Lijin Zhancheng Laser Intelligent Manufacturing Company has become popular in overseas markets this spring. This equipment can not only use laser to quickly cut steel, but also freely swing on steel, "showing" beautiful pictures. The laser travels like a paintbrush flying, and the hard steel plate has been hollowed out into be...
Recently, the High Power Laser Element Technology and Engineering Department of the Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, has made progress in the research of composite based picosecond mirrors. The related research results were published in Optics and Laser Technology under the title of "Hybrid Material Based Mirror Coatings for Picosed Laser Applications"....
IntroductionIn recent years, inspired by insect compound eyes, artificial biomimetic compound eyes have shown great advantages in overcoming the limitations of existing imaging devices such as large, bulky, and heavy, and improving the performance of medical endoscopy, panoramic imaging, micro navigation, and robot vision due to their unique optical imaging solutions such as small size, distortion...
Infrared imaging and sensing technology can be used in various fields, from astronomy to chemistry. For example, when infrared light passes through a gas, sensing changes in light can help scientists identify specific properties of the gas. The use of visible light may not always achieve this sensing.However, existing infrared sensors are bulky and inefficient. In addition, due to the use of infra...
