The data taken supports the development and characterization of a near-infrared absorption spectroscopy system. Near infrared spectroscopy (NIR) is a technique that can be used for several applications, for example in analytical chemistry. However, the method requires a high SNR which mostly constrains very accurate analysis to costly lab instruments with very low noise levels. We have applied a supercontinuum laser in a fully fiber-coupled system for acqeous measurements and characterized the SNR with different components. A case study with glucose measurements was conducted with the full system. A paper has been submitted on the analysis and is in review.

Matlab, R2021a

The data was collected using a system built in our labs outlined in the submitted paper.

The absorption data is the difference between the sample arm and reference arm. Both the unprocessed and preprocessed data is published here, see descriptions of the preprocessing under the data set in question.
