Abstract
A blind source separation model out of statistical information principle is applied to “decode” multi-gas photoacoustic spectroscopy from mixing signal into a couple of single independent component based on samples from a given detection experiment and A FastICA algorithm with used in the mode is introduced to separate the spectroscopy of low molecule mass by a feature extraction or to track that of higher-mass volatile molecule by a pattern recognition, such as acetone or its similar-species molecules. The research has exhibited its glamour by successfully extracting ammonia feature absorption in the real-time detection of breath ammonia in vivo.
