I want to setting imageDelta of fftpsf on ZOS-API-MATLAB


 


my matlab code is below


 


I wonder How can I command imageDelta.


When I try ' newWin_Settings.ImageDelta = 0.5; '


There's some error with ' Attempted to index object 'null' '


 


In ZOS-API help document, We can handle imageDelta with 'double'


 


How do I input into MATLAB so I can change imagedelta of fftpsf?



 


my MATLAB code... 


----------------------------


    TheAnalyses = TheSystem.Analyses;

    newWin = TheAnalyses.New_FftPsf();

    newWin_Settings = newWin.GetSettings();

    newWin_Settings.SampleSize = ZOSAPI.Analysis.Settings.Psf.PsfSampling.PsfS_512x512 ;

    newWin_Settings.ImageDelta = 0.5; 


    

    newWin.ApplyAndWaitForCompletion();

    newWin_Results = newWin.GetResults();

     

   dataSeries = newWin_Results.DataSeries(1);

    psf= dataSeries.YData.Data.double; %psf


----------------------------

Hello,


I have connected Matlab with the Interactive extension on \Zemax\Samples\Sequential\Objectives\Cooke 40 degree field.zmx. I then tried this:


TheApplication=ans;

TheSystem = TheApplication.PrimarySystem;

newWin = TheSystem.Analyses.New_FftPsf();

newWin_Settings = newWin.GetSettings();

newWin_Settings.ImageDelta= 0.8;

newWin.ApplyAndWaitForCompletion();

It works well and then I can see on the interface that it works.


Then for the results, you can check what the is returned:



 


As you can see, the FFT PSF does not return a DataSeries but a DataGrid.


So the syntax would be:


newWin_values =newWin_Results.GetDataGrid(0).Values.double;

This would be a matrix of values. You may want to have a look at that article: https://my.zemax.com/en-US/Knowledge-Base/kb-article/?ka=KA-01650


Do not hesitate if you have any further questions.
