Optimizing a Basler Tri-linear color camera setup

The objective of this application note is to describe a procedure that we use at Basler to test the setup of our tri-linear cameras. This description will provide you with some tips that will aid you when optimizing a tri-linear camera setup in your own system.

The document contains the following information:

• A comparison of the pros and cons between different color separation methods (tri-linear CCD, 3 CCD with prism, Bayer pattern)
• Information about the test setup (drum setup to test the functionality of line scan cameras in real world applications)
• General adjustments (e.g. optical setup)
• Causes for discolorations and other artifacts
• Information you should observe when you use digital encoders or shaft encoders
• Test results for the standard deviation of the saturation at various aspect ratios
• Conclusion
