Thus, to resolve this, you should be resolving an electrical signal at 6 ps tops. No easy task at all.<br /><br />I thought of triangulation at first, too, but laser safety was prime. Thus they used a low frequency laser that is considered safe even for accidental long exposures.<br />See this article from Fraunhofer Institute for Details:<br /><br />http://www.ipm.fraunhofer.de/content/dam/ipm/de/PDFs/produktblaetter/OFM_Optische_Fertigungsmesstechnik/BMT_Bahnmesstechnik/PPS_en_web.pdf<br /><br />Or navigate to Fraunhofer IPM -> Transport & Logistics -> 3D Road surfaces.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1924948806084793655.post-75333050014766844232013-04-11T07:49:36.947-04:002013-04-11T07:49:36.947-04:00Why do you think it's not a "regular"...Why do you think it's not a "regular" laser scanner?
