We report on low-coherence, near-infrared reflectometry applied to optical fibres, waveguides, and coupling devices to detect the echoes due to reflective propagation defects and measure their optical properties — losses or attenuation, dispersion. This technique, based on interferometry, leads to the highest spatial resolution and the lowest detectable reflected optical power. We scan the reference arm of our Michelson interferometer around the ``white light fringe'' position and obtain interferograms whose envelopes and fringes contain information on the light source spectrum and the reflectivity of the test arm. Theoretical and experimental results are compared. Examples are given and show that numerical simulations are needed to understand the signatures of the reflectors and get to their physical structures.

The refractive index of the methanol-water mixture depending on the wavelength at different concentrations was determined by our experimental method using a Michelson interferometer system. A comparative study of Gladstone-Dale, Arago–Biot and Newton relations for predicting the refractive index of a liquid has been carried out to test their validity for the methanol-water mixture with the different concentrations 30%, 40%, 50%, 60%, 80%, and 100%. The comparison shows the good agreement between our experimental results and the results in the expressions studied over the wavelength range approximately from 450 to 850 nm.

Theory And Experiment

The visibility of the channelled spectrum, or in other words the visibility of the spectral density modulation at the exit of a Michelson interferometer illuminated with a parallel beam of white light, is theoretically independent of the frequency and path difference of the two beams formed in the interferometer. Up to now there has been no agreement between theory and experiment. It is shown here, theoretically and experimentally, that the decrease in visibility with increasing path difference is related to both the finite size of the slits and the limit of resolution of the apparatus.

The development of Fourier transform infrared (FT-IR) spectrometers in the mid-1960s followed along three lines. Interferometers for far-infrared FT spectrometry typically had a slow scan speed and the beam of radiation was modulated by a rotating chopper. Several instruments based on this system were developed commercially. Very high-resolution near-infrared FT spectrometers were based on cats-eye retroreflectors mounted in a step-scan interferometer; the beam of radiation was usually modulated by dithering one of the cats-eyes (phase modulation). No commercial instruments based on this principle were developed. In the third type of FT spectrometer, the beam was modulated by rapidly scanning one of the mirrors of a Michelson interferometer. While the early instruments based on this principle only gave rise to low-resolution spectra, the incorporation of laser fringe referencing at the end of the decade led to instruments that were the fore-runners of contemporary FT-IR spectrometers. In this article, the author’s experiences with instruments of the first and third category are described.
