Using laser-based analysis techniques on Mars with the ChemCam and SuperCam instruments

Submitted by soleson@lia.org on

The NASA Curiosity rover has been exploring the surface of Mars for the past eight years, carrying with it the ChemCam instrument as part of its scientific payload. ChemCam is a suite of instruments that includes a laser-induced breakdown spectroscopy (LIBS) instrument, which provides chemistry information about geologic materials at standoff distances of up to 7 m from the rover. The ChemCam LIBS instrument has produced over 800,000 individual spectra, an unprecedented number of observations from a single instrument on Mars.

Past Present and Future of Metallic Additive Manufacturing

Submitted by soleson@lia.org on

Economist Magazine hailed Additive manufacturing (AM) as “Third Industrial Revolution”. AM also features prominently in Factory 4.0. It has been practiced in one form or other for more than 5000 years. A pyramid in Egypt was built at 2800 BC using layer-by-layer construction. Modern versions for this technology are around for almost three decades. The first patent on steriolithography was issued in 1986 to Charles Hull. In many ways it is “back to the future”

For a brighter future of the global society, Japan is committed to achieving sustainable growth and becoming a pioneer in the establishment of a new social model Society 5.0. Society 5.0 is defined as a human-centered society that balances economic advancement with the resolution of social problems by a system that highly integrates cyberspace and physical space, i.e., cyber-physical system (CPS).

Quality assurance in laser-based, metal additive manufacturing: Generation and detection of systematics and stochastic defects

Submitted by soleson@lia.org on

Laser-based powder bed fusion (PBF) and directed energy deposition (DED) additive manufacturing have been embraced by much of the aerospace and defense industry for part production and repair. Unfortunately, there still remains considerable uncertainty regarding the causes and effects of many defects types observed in PBF and DED components. Numerous conditions can lead to the formation of defects (i.e. internal discontinuities or undesirable microstructure) that can negatively affect build and part quality. Some of these defects are easily attributable to systematic errors (e.g.

Biophotonics Success and Future: Where have we been and where do we go next

Submitted by soleson@lia.org on

Since before the first studies of Endre Mester with the Ruby laser where he showed accelerated wound healing, biophotonics has demonstrated transformational solutions in Medicine. This talk will present a review of several successes biophotonics has had in Medicine and new opportunities. Devices including Laser Scribing, OCT, Refractive Lasers, and Femtosecond Laser-Assisted Cataract Surgery have transformed the standard of care in Medicine. As we look back and to the future, what is next for biophotonics in Medicine? Transformation of aphakic IOLs? COVID-19 detection? Drug fabrication?
