To address the CBD’s need for real-time analytical technology for multicomponent vapor identification and quantification, Physical Optics Corporation (POC) proposes to continue the development of a new Photoacoustic Gasses Optical Detector and Analyzer (PAGODA) autonomous, network-enabled photoacoustic spectrometer (PAS) for the correlation, analysis, and identification of measured spectra. In the Phase I effort POC has designed, fabricated, and tested the PAGODA system conceptual prototype, including the MEMS PAS transducer prototype, identified means to improve the spectral resolution and sensitivity, and derived the preliminary design constraints for a Phase II PAGODA demonstration system. Phase I results confirmed the ability of the PAGODA system to meet CBD requirements for the detection and quantification of airborne chemical threats with spectral resolution of ~200 nm by continuously monitoring atmospheric vapor and aerosol components while using standard batteries, weighing
