Abstract：Turlun structure was introduced into the Fourier transform interference system in the present paper in order to decrease the size and cost of the whole system and to increase the ability of vibration resistance to meet the requirement of car-borne outdoor monitoring application. The speed deviation of the voice coil motor (VCM) driving system, which is based on feedback of interference wavelength of reference laser and DSP control, is within 5%. The standard oil sample was used to test the performance of the spectrometer. The result shows that the highest resolution of the FTIR oil detector is 2 cm-1, and the SNR reached 2 000∶1. Compared with old grating spectrometers, this kind of instrument is faster, and the quality of spectrum was increased significantly. The portable feature of this instrument will be more convenient for the water pollution detection in field.
