研究目的
To develop a dynamic Fourier transform spectrometer for recording Raman spectra in the near-IR range (800–1100 nm) with improved stability, reliability, and signal-to-noise ratio.
研究成果
The dynamic Fourier transform spectrometer successfully recorded Raman spectra of test substances with qualitative agreement to diffraction spectrometer results but in a quarter of the time. The design's white light and reference channels enabled effective signal accumulation and improved signal-to-noise ratio. Future enhancements aim to further increase signal intensity and spectrometer performance.
研究不足
The spectrometer's performance is limited by the sampling error when moving away from the center of the interferogram, affecting signal-to-noise ratio and spectral resolution. Future improvements include integrating the Raman attachment directly into the optical system and replacing the radiation detector to increase entrance aperture and light-gathering power.
