Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
Scientists at the University of Chicago have demonstrated a way to create infrared light using colloidal quantum dots. The researchers say this approach shows great promise; Although the experiment is still in its early stages, these quantum dots are already as efficient as existing conventional methods.These points could one day form the basis of infrared lasers, as well as small and inexpensive ...
According to research from Busan National University, inorganic perovskite materials are easy to prepare and process, making them suitable for manufacturing lasers.The perovskite of interest is CsPbBr3, which must form "nanosheets" within the specific structure invented by the Busan team to obtain sufficient laser gain.It is not that the laser has been achieved, as the research project aims to cha...
FOSTEC announced on the 8th that a new type of fiber fusion splicer has been launched. The newly launched FS-23 series is a fusion splicer that can be used for fiber optic operations in long-distance optical networks and CCTV optical networks. It not only has a small size and light weight, but also has a sturdy design and a long-lasting battery, which can provide high-precision performance.A perso...
