Paper Abstract

A new technique utilizing harmonic Fourier spectra created by the non-linear properties of a compact Fourier transform infrared interferometer (FTIR) was proposed and realized to improve the system resolution. The compact standing wave FTIR (SWFTIR) system consists of a partial transparent hetero-junction bipolar phototransistor (HPT) and a free scanning highly reflective mirror. The overall size of the system is less than 5×5×5cm3, and the resolution at 1.5μm is better than 37.5cm-1 at the 5th harmonic spectral component. The SWFTIR array system has theoretical resolution of better than 1cm-1 covering the whole near-infrared region with potential compact portable applications.
