3D imaging using the triangulation technique

About the C3-1280-CL camera
Acquiring height profiles and height images by means of laser sheet-of-light (triangulation) technique, a laser line is projected on the object, the resulting sensor image being evaluated by the camera core and converted into a single height profile By scanning the laser line over the object, a complete height image of the object can be acquired.

The camera's ability to complete the 3D calculations inside the camera enables it to acquire up to 47 000 profiles per second with more than 60 million 3D points per second. For maximum flexibility, three profile algorithms are included without the choice of the profile influencing the profile speed. This results that the profile date are always output at the same maximum speed.

The C3 sensor is capable of delivering position data as well as additional features (eg intensity, line width) without sacrificing profile speed. An additional feature of the camera is that up to eight sensor AOIs can be designed for dividing the sensor in separate subwindows. The sensors are equipped with a global snapshot shutter for capturing sharp, undistorted images and profile data even for fast-moving objects.

The camera's advanced trigger options assures precise profile triggering even at changes of movement velocity.
