Fast Fourier Transform Spectrum Analyzer: Construction of a Fast Fourier Transform Spectrometer and Analysing Characteristic Spectrum of Light Emitting Diodes
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
In this work a Fast Fourier Transform (FFT) spectrometer with a He-Ne laser as a reference is constructed from "off-the-shelf components" to investigate the spectrum of high luminescent diodes. The resolution of the spectrometer was calculated to be 4.7 GHz and the measured spectra were in accordance with the diodes specifications. The diodes measured were B42182 and N42182 of Seoul Semiconductors whose band gap and composition was determined based on the information from their characteristic emission spectrum.
