Linescan
imaging is complicated, color machine vision is tricky too. Putting
the two together sounds like something only the bravest (or most
foolhardy) vision engineer should attempt. Yet there are times when
it has to be done.
Anyone
needing to dip a toe in these murky waters would do well to learn
more about the camera options. To that end, Dr. Xing-Fei He of
Teledyne Dalsa authored “Trilinear
Cameras Offer High-Speed Color Imaging Solutions”,
published in the May 2013 edition of Photonics Spectra.
This
compares and contrasts the three types of color linescan camera,
giving the potential user an understanding of what to look for. Of
course, price is left out of the article, but rest assured it
correlates with performance, though not necessarily in a linear
manner.
Happy
(color) scanning!
