WebMar 31, 2024 · The RMS wavefront error (found by building a default wavefront Merit Function) is 2.15 10^-3 waves, which may be lower than you might expect by visual inspection of the OPD plot. Note however that the aperture definition of this system uses Gaussian apodization. WebOct 19, 2005 · Optical State Estimation provides a framework for both separating errors in test optics from the target system and deducing the state of multiple optics in a telescope beam train using wavefront as well as pre-test component measurements including the knowledge of their level of error.

C. Redding and John Z. Lou and Yan … WebAbstract. Modal estimation of wave-front phase from phase derivatives is discussed. It is shown that it is desirable to minimize the number of modes estimated and the number of measurements used to maintain the quality of the estimates of low-order modes. It is also shown that mode cross coupling occurs when one tries to estimate modes higher ...
