The team of Wu Dong, professor of the Micro/Nano Engineering Laboratory of University of Science and Technology of China, proposed a processing strategy of femtosecond laser two in one writing into multiple materials, manufactured a micromechanical joint composed of temperature sensitive hydrogel and metal nanoparticles, and then developed a multi joint humanoid micromachine with multiple deformat...
The emergence of laser inner glass carving technology has brought new forms and possibilities of artistic expression to glass art. It not only showcases advanced technology and innovative craftsmanship, but also endows glass works with unique artistry.Firstly, laser engraved glass can achieve very fine and complex carving effects. By penetrating the interior of glass with a laser beam for carving,...
The time/frequency unit is the most accurate among the seven basic units, so many measurement studies that pursue ultra-high accuracy and sensitivity will be transformed into frequency measurements to achieve higher measurement accuracy and sensitivity. For example, by measuring the relative changes in the ratio of different atomic transition frequencies, ultralight dark matter can be detected or ...
Winning the SEMA Best Engineering New Product Award is not an easy task. Therefore, it said a lot about Huali's new non floating fuel transmitter bringing hardware home. The Easy Level fuel level sender is a brand new design that does not rely on traditional float arm settings, but uses a frikken laser beam to measure the fuel level in the tank.More precisely, Easy Level uses LiDAR technology to m...
The new device is a frequency comb - a special type of laser that can generate multiple wavelengths of light, each with a fixed frequency interval. On the spectrogram, it looks a bit like the teeth of a comb. In approximately a quarter century since their first development, these "cursor rulers" have completely transformed various high-precision measurements from timing to molecular detection. In ...
