A simple configuration for static Fourier transform infrared spectrometers

Official URL: http://dx.doi.org/10.1117/12.2228313

In this work we have proposed a new configuration based on a tilted charged coupled device (CCD) camera and bandpass sampling theorem which not only decreases the spectrometer size but also operates in the traditional spectrometers wavelength range of 400 nm – 1100 nm. The static Michelson interferometer is built by attaching a quartz cube and a prism together, and a CCD camera is attached to the quartz cube in 45 degree to record path length differences (PLD). An algorithm is developed to process the signal and calculate the Fourier transform of the recorded interferograms on the CCD camera.
