Abstract: Fourier transform spectroscopy is known as a powerful tool for measuring weak radiation with high resolution. Commonly, Fourier transform spectrometers use highly precise scanning mirror mechanisms to obtain spectral information resulting in large scale and high cost spectrometers. Miniaturization of spectrometers may overcome the cost and size limitation of the instrument at the expense of resolution. Such miniature, lower resolution spectrometers however allow a wide range of attractive applications in science and industries. This thesis reports the development, fabrication and testing of miniaturized stationary lamellar spectrometer, dubbed the Fast Parallel Process Fourier Transform Interferometer (FPP FTIR). A prototype spectrometer operating in the fingerprint region of the infrared spectrum at a theoretical resolution of 25 cm-1 was fabricated and tested. No moving parts, small size, sturdy design, fast data acquisition and real-time spectral sensing are characteristic properties of the spectrometer. Emphasis of this work is put on the fabrication of three dimensional diffractive optical elements forming the core of the spectrometer.
