The Advantages of Line Confocal Imaging over Coaxial Confocal Imaging

The key advantage of line confocal sensors is their ability to generate 3D tomography, 3D topography and 2D intensity data simultaneously over a 2 k line scan at fast scan rates (namely up to 3 kHZ at full measurement range). Line confocal scanning avoids unwanted reflections from shiny metal surfaces and the off-axis arrangement permits multi-layer (tomography) scanning.
