The fully 3D printed electric spray engine is suitable for small satellite in orbit maneuver, and its production cost is only a small part of that of traditional thrusters.Image source: Massachusetts Institute of Technology, USAThe Massachusetts Institute of Technology team recently demonstrated an electric spray engine made entirely of 3D printing technology, which can be propelled by emitting ...
Physicists from the University of Heriot and the University of Cambridge have developed an innovative laser system called Astrocomb, which can significantly improve the detection of exoplanets. This advanced tool can accurately measure the spectra emitted by nearby stars, which fluctuate due to the gravitational influence of orbiting planets. It is expected that this technology will enhance resear...
Recently, the research team of Aerospace Laser Technology and System Department of Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, based on 2.1 μ M Ho: YAG main oscillator amplifier pumped ZGP crystal, achieving high energy 3-5 at kHz repetition frequency μ The output of M medium wave infrared laser and further research on beam quality improvement technology for high-...
At present, the navigation system has become an important equipment on ships, aircraft, missiles, automobiles and other navigational vehicles. Laser Doppler radar has become an important development direction in the field of velocity measurement technology because of its high accuracy, good spatial resolution and fast dynamic response. The application of the three-beam Doppler Lidar in the...
German researchers have developed a method for controlling and manipulating optical signals by embedding liquid crystal layers into waveguides created by direct laser writing. This work has produced devices capable of electro-optic control of polarization, which may open up possibilities for chip based devices and complex photonic circuits based on femtosecond write waveguides.Researcher Alexandro...
