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...
Snapmaker has opened pre-orders for 20W and 40W laser modules, which are significant upgrades to the modules available on existing Snapmaker machines.Snapmaker says that with the 40W module installed, you will be able to cut 15 mm basswood plywood at a time at a speed of 20 mm/SEC. With 20W, you will cut 10mm at a rate of 10mm/SEC. That's a lot more than Artisan and Snapmaker 2.0 - both are comp...
A group of researchers from the Max Planck Institute for Material Structure and Dynamics in Germany explored the effect of manipulating the properties of quantum materials far from equilibrium through customized laser drivers. They found a more effective method to create previously observed metastable superconducting states in fullerene based materials using lasers.By tuning the light source to 10...
On September 5, when Mei Xin Sheng held an analyst meeting, it said that the company has launched a fully integrated ultra-low power optical proximity detection sensor and a three-in-one ambient light and proximity detection sensor with ultra-high sensitivity, which have entered mass production.The research and development of high-precision polarized light crown products has been completed, the fe...
When observing biological samples under a microscope, if the medium in which the objective lens is located is different from the sample, the light beam will be interfered with. For example, when observing a water sample with a lens surrounded by air, the light bends more strongly in the air around the lens than in water.This interference can cause the measured sample depth to be smaller than the a...
