Abstract [en]

A Fourier transform spectrometer (FTS) was constructed to analyze the light of a white LED. The spectrometer utilizes re-sampling with the help of a reference interferogram from a HeNe laser. The resolution was estimated from the measured line width of the re-sampled HeNe laser and was found to be in the order of 0.4 nm. The spectrum collated from the white diode had a signal to noise ratio of 350 which was more than sufficient for our purposes. The measured spectrum point towards the light being produced by a combination of red and blue LED:s and a phosphor layer of YAG:Ce providing the green-yellow colors.
