Contrast Loss Map in OpticStudio 17.5

Contrast Loss Map is a new feature in OpticStudio 17.5 that provides an easy way to understand how contrast varies or is lost in an optical system. It visualizes contrast loss for a specific frequency of the Modulation Transfer Function (MTF) as a distribution map across the exit pupil. Contrast Loss Map gives insight into how the MTF is degrading across the pupil. You can then use the data to determine what changes to make to your system to improve MTF. Contrast Loss Map plots the same contrast loss values that are calculated during Contrast Optimization, a new capability introduced in OpticStudio 17 that uses the Moore-Elliott method to optimize for MTF at least 30 times faster than traditional methods.

Optimizing for MTF Performance using Contrast Optimization

Our new Contrast Optimization technique allows for robust and efficient optimization on the system MTF at a given spatial frequency. The method minimizes the wavefront differences between pairs of rays separated by a pupil shift corresponding to the targeted spatial frequency, which maximizes the MTF. Further computational efficiency is achieved by using Gaussian Quadrature to determine the pattern of rays sampled. Examples are given to demonstrate the advantages of the technique.
