…projector. These distorted
perspectives can be used for an exact geometric
reconstruction of the surface shape.
In a typical 3D triangulation sensor, the laser line
provides two of the three dimensions of the object. The
third is obtained by moving the object with respect…

Growing Need for 3D Inspection".)
Key laser projector parameters for this application are line straightness,
uniform line thickness, and high pointing stability. Good line brightness
uniformity is also desirable but not mission-critical. Red (diode-based)
modules have been…

…object with the light constructs 3-D information about the shape
of the object.This is the basic principle behind depth perception for machines,
or 3D machine vision. In this case, structured lighting is sometimes described as
active triangulation.
Since structured lighting can…
