Can I use the Fourier Transform to analyze the Sun's Spectrum?

Click For Summary

Discussion Overview

The discussion centers around the application of the Fourier Transform (FT) in analyzing the Sun's spectrum, exploring its usefulness and the necessary considerations for such an analysis within the context of astrophysics and digital signal processing.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant expresses interest in applying the Fourier Transform to analyze the Sun's spectrum and seeks opinions on its usefulness and requirements.
  • Another participant questions the intent behind using the Fourier Transform, noting that the spectrum is already represented in the frequency domain.
  • A third participant claims that the Sun's spectrum can be viewed as the Fourier transform of solar radiation.
  • A later reply suggests looking into Fourier Transform Infrared Spectroscopy (FTIR) while raising concerns about its applicability in the visible and ultraviolet ranges.

Areas of Agreement / Disagreement

Participants present multiple perspectives on the application of the Fourier Transform to the Sun's spectrum, indicating that the discussion remains unresolved with competing views on its usefulness and applicability.

Contextual Notes

There are limitations regarding the assumptions about the spectrum's representation and the specific conditions under which the Fourier Transform may or may not be applicable, particularly in different wavelength ranges.

I'm learning digital signal processing in my engineer class, but I'm more interested in apply these things into Astrophysics, so i know a little bit about for what is useful the Fourier Transform, so i thought why not use this in Analyzing the sun spectra! But what do you think!? Is it useful!? What do i need !?

What are you trying to learn from this? Remember, the spectrum is already in the frequency domain.
 
Sun's spectrum is Fourier transform of solar radiation.
 
Look up FTIR, then consider why it won't work in visible and UV.
