Title:
ラマン分析器
Document Type and Number:
Japanese Patent JP3181863
Kind Code:
U
Abstract:
A method of diagnosing a health problem in a patient by determining the isotope ratio in exhaled human breath using a Raman analyzer is provided. The Raman analyzer for analyzing light emitted from a Raman cell used in the method has a beam splitter configured to split the light emitted from the Raman cell into a first beam and a second beam. An atomic vapor filter can be used to filter a Raman scattered line from the first beam and a chopper system can periodically interrupt the first and second beams that are directed towards a photo detector, which can convert light from the first and second beams into an electrical signal. The signal output from the photo detector can optionally be amplified, digitized, Fourier filtered, and/or subjected to Fourier analysis.
