C2 Series Overview
Introduction
The C2 camera series is a revolutionary product family of intelligent high speed sensors. It is
optimised for 3D profile measurement by means of laser triangulation technique. The 3D profile
extraction is performed in the camera by using high performance Field Programmable Gate Array
processors. At the same time the 3D profile data is sent to the PC over a Gigabit Ethernet interface
(GigE). This extreme data reduction boosts the measuring speed to unprecedented levels without
affecting the performance of the connected image processing unit.
