摘要：
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 5x5x5cm(3), and the resolution at 1.5 mu m is better than 37.5cm(-1) at the 5(th) harmonic spectral component. The SWFTIR array system has theoretical resolution of better than 1 cm(-1) covering the whole near-infrared region with potential compact portable applications.
