Decomposing circular diffraction patterns
I have the following diffraction pattern produced by a fabry-perot etalon
The red represents the center of that pattern. Taking the mean intensity of the pattern as a function of the radius from the ...

How to model the effects of diffraction for a convex lens?
I am using a convex lens in a wavefront-measuring interferometer for testing microscope objectives, where the lens images the exit-pupil of the objective onto my camera. It is my understanding that ...

What is called the diffraction phase in an interferometer?
I'm reading articles about atom interferometers using Bragg diffraction to split the atom beam. It says the beam splitter causes an unwanted phase shift between transmitted and reflected waves? So ...

Bandpass of diffraction grating - exit slit width?
I'm supposed to derive a relation for the range of wavelengths that's being transmitted by a spectrometer (bandpass) in terms of the dispersion, focal length and exit slit width.
Given grating is $...

Fabry Perot Etalon - changing wavelength and plate distance
Given reflectivity $R = 0.75$, an etalon is used as an interference filter, transmitting light of wavelength $4.3\mu m$ at normal incidence. The full width half maximum is about $\Delta \lambda = 0.2 \...
