Abstract

The paper presents a schematic diagram of the experimental setup human breath analysis using a broadband infrared quantum-cascade laser and a multipass Herriot gas cell. The sensitivity of described experimental setup allows to detect most common biomarkers of various diseases. The experimental spectra for several test substances are measured, threshold concentrations are detected. Statistical numerical methods and deep learning for spectra analysis are considered.
