Hello!
I am getting two different results for the exact same optical system by simply changing which field I am looking at when computing the huygen’s mtf. All I did was change Field from “All” to “1” and the MTF for the same field increased when I switched it to “1” and matches the FFT version much closer then when “All” is selected. Why would that be the case? I have 5 fields, one wavelength.
