Please can someone provide me with an explination about how a FTIR machine works?

    1. The problem statement, all variables and given/known data
    Im having a real problem trying to imagine what happens inside the machine can anyone help? I thought that at the interferometer a beam is split into two and then recombined with a path difference to introduce interference. Because the IR source is broadband would all of the waves interfere which each other to produce the beat phenomenon when out of phase and interact constructively when there is no phase difference? What I am trying to ask is that after the beam splitter is there only one resultant wave which reaches the detector? I just dont know how a fourier transform infra red machine is capabale of detecting all of the IR frequencies simutaneousily? Please help

    2. Relevant equations

    3. The attempt at a solution
