The temporal and spectral characteristics of femtosecond lasers were exploited in absolute distance measurement by means of pulse cross-correlation based interferometer and dual-comb interferometer which enable nanometer precision not only in laboratory environment but also in open-field. In this talk, absolute distance measurement technique will be described after brief introduction of femtosecond lasers and second half of the talk will be devoted to feasibility test of absolute optical testing exploiting distance measurement overcoming relative testing nature of conventional laser interferometer.<\/p>\n<p><span style=\"font-size: 16px;\">For more information, please contact Dae Wook Kim \u2013 dkim@optics.arizona.edu<\/span><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Dr. Joohyung Lee Korea Research Institute of Standard and Science (KRISS) 3:00 PM \u2013 Thu \u2013 June 20th \u2013 2013 Conference Room 821 Femtosecond lasers offer unique characteristics in both the temporal and spectral terms, not observed in other continuous-wave or pulse lasers, permitting breakthroughs in precision dimensional metrology particularly.
