摘要	This Letter reports a new optical fiber gas sensor for measuring breath acetone. The sensor is based on photonic bandgap (PBG) mode laser emission sensing technology using liquid crystal (LC), which is combined with silica fiber and chiral nematic liquid crystal (CNLC), thus providing an ultra-compact, fast-response and simple-to-produce sensing system with a fast response that can accurately and quanti-tatively determine the concentration of respiratory acetone within the normal oral temperature range (35-38 degrees C). Since LCs are affected by temperature, we propose a method that eliminates the influence of the temperature to solve the prob-lem of the temperature influence when measuring gas. The detection of acetone leads to splitting of the dual laser peaks, with a linear correlation of 0.99. The sensor has a limit of detection of 65 ppm for acetone vapor and thus is suitable for breath acetone detection in diabetic patients. (c) 2023 Optica Publishing Group
