Researchers at the Federal Institute of Technology in Lausanne have resolved the long-standing debate surrounding laser additive manufacturing processes through a groundbreaking defect detection method.The development of laser additive manufacturing is often hindered by unexpected defects. Traditional monitoring methods, such as thermal imaging and machine learning algorithms, have shown significa...
Improvements in LiDAR technology will assist NASA scientists and explorers in remote sensing and measurement, surveying, 3D image scanning, hazard detection and avoidance, and navigation.Like sonar that uses light instead of sound, LiDAR technology is increasingly helping NASA scientists and explorers with remote sensing and measurement, surveying, 3D image scanning, hazard detection and avoidance...
It is reported that recently researchers from the Chinese Academy of Sciences have achieved the highest power output of 193 nm and 221 nm lasers using lithium borate (LBO) crystals. This achievement lays the foundation for the further application of the laser in deep ultraviolet (DUV) spectroscopy.The laser in DUV spectroscopy has many applications in science and technology, such as defect detecti...
The most famous use of GPS satellites is to help people understand their location, whether it is driving cars, ships or planes, or hiking in remote areas. Another important but little-known use is to distribute information to other Earth observation satellites to help them accurately locate measurements of our planet.NASA and several other federal agencies, including the US Space Force, the US Spa...
Recently, optical semiconductor developer Lumiotive, headquartered in Seattle, USA, launched a new LiDAR sensor LM10, which is its first fully produced product of light controlled metasurface (LCM) technology designed for digital beam steering.The developers stated that compared to mechanical systems, their digital beam steering method overcomes the limitations of traditional LiDAR sensors in term...
