At a distance of 325 meters, the human eye may only be able to distinguish between a person's head and body, making it difficult to discern any other differences. But a research team including Heriot Watt University in the UK and Massachusetts Institute of Technology in the US has developed a new type of LiDAR scanner that can perform detailed analysis of a person's face from such a distance and c...
The China International Industrial Expo is an important window and economic and trade exchange and cooperation platform for China's industrial sector to the world, as well as a window for the world to understand the current development status of China's manufacturing industry. It is understood that the scale, energy level, and number of new exhibits of this year's Industrial Expo are all the highe...
A new article published in Optoelectronic Science reviews the basic principles and applications of optical capture of optical nanoparticles. Optical nanoparticles are one of the key elements in photonics. They can not only perform optical imaging on various systems, but also serve as highly sensitive remote sensors.Recently, the success of optical tweezers in separating and manipulating individual...
Femtosecond laser emits ultra short light pulses with a duration of less than 1 picosecond, reaching the femtosecond domain. The characteristics of femtosecond lasers are extremely short pulse width and high peak intensity.Ultra short blasting can minimize waste heat, ensure precise material processing, and minimize incidental damage. Their peak intensities can cause nonlinear optical interactions...
