Cognex 3D Displacement Sensors
Cognex 3D displacement sensors combine GigE Vision and laser-stripe illumination to generate information about
three-dimensional objects that cannot easily be generated by cameras that acquire two-dimensional images. Each
sensor projects a triangular laser plane onto an object as it passes within view.
The illumination of the laser plane generates a laser stripe whose shape is determined by the surface of the object.
The integrated camera uses a red long-pass filter to capture an intensity image of the laser stripe:
