Contrast Optimization – A Faster and Better Method for Optimizing System MTF

July 26th, 2017



Zemax has developed a new optimization theory called Contrast Optimization, which targets the best MTF response at a desired spatial frequency. Optimization of the MTF is especially useful for extended images with cutoff frequencies set by the detectors, since lower spatial frequencies can be improved at the expense of higher, unneeded frequencies. But optimizing directly on the MTF value is slow, difficult, and often fails. Contrast Optimization increases the MTF in a much more robust way, and is just as fast as optimizing on the RMS wavefront. 

This webinar will demonstrate how to: 
· Show the theory behind Contrast Optimization
· Demonstrate how to use Contrast Optimization to achieve the best MTF values 
· Show why Contrast Optimization is more robust than direct optimization of the MTF 
· Show how Contrast Optimization simplifies the optimization parameter space, so that the optimization finds the best possible design more quickly
