Introducing FocalSpec® 3D Line Confocal Sensors insights from industryTerry ArdenChief Executive OfficerLMI Technologies In this interview, AZoSensors talks to Terry Arden, Chief Executive Officer at LMI Technologies, about their FocalSpec® 3D line confocal sensors. To begin, can you give us an introduction to FocalSpec® 3D line confocal sensors? Can you tell us about how FocalSpec® sensors utilize line confocal imaging (LCI)? FocalSpec® sensors use line confocal imaging technology, a patented optical technique where white light emitting from a sensor's transmitter is split into a continuous spectrum of wavelengths and projected onto an object such that each wavelength maps to a unique height position.
