Hi there, optical aberrations can be expressed by Zernike polynomials Vmn(ρ,θ). Now, for my simulations i am using software that takes 4 inputs for creating aberrations onto an optical flat: m,n,R,A m,n are the Zernike orders which is perfectly clear. For R,A the manual says: R: the radius A...

I use a simulation software which initializes an optical field and i instantly create the lens afterwards, so the optical field source and the lens are on top of each other. The software uses Fourier optics for the simulation. All i specify is the focal length, wave length and aperture size. My...

Hi blue_leaf77, thanks for your answer. The problem is, i don't have 2 spherical wave emitted by a point source. I have an extended light source with radial aperture transmitted through a positive lens, see picture original post. I still don't see how the center of the interference fringes...

Hello everyone, i am simulating a Michelson interferometer, where one mirror is slightly tilted, see picture.. This results in circular arcs / hyperbolic cross-section fringes. The center of these fringes depends on the focal length i am using, see picture. Is there an analytical expression for...
