IR Spectrometers

3.1K
There are two main infrared (IR) spectrophotometers: dispersive IR spectrometers and Fourier transform infrared (FTIR) spectrometers. In a dispersive IR spectrometer, a beam of infrared radiation produced by a hot wire is divided into two parallel equal-intensity beams using mirrors. One beam passes through the sample, while another is a reference beam. The beams then move through the monochromator, which separates the radiations into a continuous spectrum of different frequencies. The...

    Area of Science:

    • Optoelectronics
    • Materials Science
    • Sensor Technology

    Background:

    • Spectral demodulation is key for Fabry-Pérot (F-P) temperature sensors, offering high accuracy and dynamic range.
    • Material dispersion in F-P cavities can cause calculation errors, limiting sensor reliability.
    • Silicon-based F-P sensors are valuable for temperature measurement but susceptible to dispersion effects.

    Purpose of the Study:

    • To develop a dispersion-compensated spectral demodulation method for silicon-based fiber optical F-P temperature sensors.
    • To address and correct for the dispersion-induced optic path difference (OPD) blue shift.
    • To ensure accurate temperature readings and prevent calculation failures in silicon F-P sensors.

    Main Methods:

    • A numerical model of the silicon sensing F-P cavity was constructed, incorporating thermal expansion and thermos-optic properties.
    • A compensation curve was developed to counteract dispersion-induced OPD shifts.
    • Simulations and experiments were conducted to validate the method's effectiveness.

    Main Results:

    • The proposed method accurately solves the cavity's OPD by compensating for dispersion.
    • Simulations confirmed no loss of precision compared to traditional spectral demodulation.
    • Experiments demonstrated the avoidance of dispersion-induced phase jump defects across a -40 to 100 °C range.

    Conclusions:

    • The dispersion-compensated spectral demodulation method effectively enhances the performance of silicon-based F-P temperature sensors.
    • This approach overcomes limitations posed by material dispersion, ensuring reliable temperature measurements.
    • The method facilitates the robust application of spectral demodulation techniques in silicon F-P sensing systems.
