2011年12月6日 · Laser-induced breakdown spectroscopy, also known as laser-induced plasma spectroscopy (LIPS), enables the determination of material elemental composition on the basis of the characteristic emission from atomic species in a microplasma that is produced by focusing a pulsed laser on the surface of a solid sample/object .

2023年11月2日 · In particular, the papers focus on the development and use of innovative spectroscopic and imaging characterization techniques, the diagnostic knowledge of important artworks, and the optimization of the laser solution for preserving a growing variety of cultural assets, such as stone and metal artefacts, painted surfaces, textile, feather, and ...

2015年9月10日 · Electrochemical impedance spectroscopy was used in situ on a selection of the tested areas in order to characterize the effect of laser cleaning on the rate of corrosion. A specially designed contact probe was used for measurements in the frequency range 100 kHz–10 mHz both before and after cleaning.

2024年4月3日 · Inspired square micro-texture structures designed by nanosecond laser sculpture for enhancing adhesion strength of plasma spraying Si-HfO₂ bond coat on SiC substrates Yu S.; Wang Y.; Wang S.; Zhao Q.; Li Y.; Ren D.; Chen G.; Zou Y.; Ouyang J.; …

Focusing a laser beam on priceless pieces of art doesn’t initially sound like the best idea, but its surprising application for cleaning could ensure the preservation of masterpieces for generations to come.

2020年10月2日 · Having over three orders of magnitude higher transmission through strongly scattering media, compared to light in the visible and near infrared, PA signals offer substantially improved detection...

Mike Gould is an internationally-recognized laser artist who builds kinetic, interactive, Neo-Op Art laser light installations into art galleries and museums. He works with Illuminatus Lasers for special events

2011年12月1日 · Studies on series of model paints performed in order to understand the sensitivity of pigments to laser irradiation are critically reviewed. In this respect the importance of the optimal wavelength and pulse-duration selection for a safe and controlled laser cleaning intervention is also addressed.

2013年5月16日 · These are a series of static light sculptures that have been created using laser light, smoke, shadows, physical shapes and custom built software to create complex compositions of shadow and light that play with the sense of depth and perception.

2021年6月15日 · The following examples show a handful of art projects where lasers were used successfully. For most of these laser art projects, artists used full-colour scanning laser display systems such as Clubmax, Atom or Spectrum. But sometimes, as shown in the 1st example, single-beam static green laser modules did the trick. Portal - Toxteth Reservoir, UK
