Helper class for modeling FQPMs accurately
Adds (or removes) a slight wavelength and pixelscaledependent tilt to a pupil wavefront, to ensure the correct alignment of the image plane FFT’ed PSF with the desired quad pixel alignment for the FQPM.
This is purely a computational convenience tool to work around the pixel coordinate restrictions imposed by the FFT algorithm, not a representation of any physical optic.
Parameters :  direction : string


Methods Summary
getPhasor(wave)  Compute the required tilt needed to get the PSF centered on the corner between the 4 central pixels, not on the central pixel itself.
