Optical metrology for advanced manufacturing
Jeff Squier | jsquier@mines.edu
Presently there are little to no meaningful optical metrics that can be usefully applied to advanced manufacturing processes such as 3D laser printing of metal components. Such metrics would be useful to provide real-time feedback to the production process ensuring a higher quality, defect minimized part. We believe we have developed a series of optical metrology tools useful for the advanced manufacturing community.

Grand Engineering Challenge: Engineer the tools of scientific discovery
Student Preparation
Qualifications
Experience with 3D printing technology –
No optics experience necessary, we will guide development in use of optics and femtosecond lasers and technology.
Time Commitment
20 hours/month
Skills/Techniques Gained
An understanding of how to apply state-of-the-art photonics technologies to real-world advanced manufacturing challenges.
Mentoring Plan
Prof. J. Squier and Dr. D. Adams (in physics) will meet weekly with the student. We will ensure that either one of us or a senior graduate student is also in the lab during the student’s lab time to help guide the research and answer questions in real-time.
