3.11 Spatial Correction

Spatial Correction and Trilinear Sensor Design
The trilinear sensor has three color lines do not share a common optical axis. This
results in the three color lines imaging three separate object points.
As a result, the color images need to be stored, delayed and recombined to properly
reconstruct the color image. This is referred to as spatial correction.
As the object travels along the web, the object passes the three color lines at different points in time.
As a result, the camera uses spatial correction to reconstruct the image.
The Piranha Color sensor uses DALSA's proprietary design to minimize the center to
center spacing to 30 µm (4k) or 42 µm (2k).
