Triangulation Schematic

This triangulation schematic shows the geometrical deformation of a single stripe projected onto a simple 3D surface. The displacement of the lines allows for an exact retrieval of the 3D coordinates of any details on the object's surface.

Structured Light Laser Triangulation Schematic


The Coherent StingRay series has been enhanced to include 50 mW output in Blue, making it especially advantageous for machine vision applications based on 3D triangulation that involve darker materials. Learn more about the new Blue laser. 

Coherent StingRay lasers enable the construction of faster and more accurate machine vision systems that use 3D Triangulation. The Coherent StingRay series mates a diode laser with high performance electronics and precision refractive optics for pattern generation covering the widest range of applications.
