How do I design a Fourier Transform Infrared Spectrometer?

Question

I need to design a Fourier Transform spectrometer to measure Zeeman splitting of a 1.0 micrometer spectral line, where the required resolution to observe the splitting is 0.1 Angstroms. What would this appartus look like? And what would the dimensions on the mirrors and mirror movement be?

Answer 1

A Fourier Tansform is a mathematical operation and cannot be built. The spectrometer should be pretty much described in journals and can probably be purchsed.
