SBIR Phase I: Inexpensive High-Performance Carbon Dioxide Environmental Monitor

小型企业创新研究（SBIR）第一阶段研究项目将确定适用于高精度检测环境中二氧化碳的廉价激光光谱仪的性能和操作规范。二氧化碳是大气中温室气体积聚的主要来源，正在影响全球气候变化。重要的是测量大的大气背景浓度的微小变化。新的传感器将大约是一罐苏打水的大小，并在几秒钟内提供十亿分之一（ppb）的二氧化碳灵敏度。完全开发的坚固耐用的原型将适用于环境领域应用中的二氧化碳长期检测。大幅提高的价格点将使这些传感器广泛分布于大气测量应用中，而不会因价格而牺牲性能。这将使导致全球气候变化的人为温室气体的测量分布更广。基本技术应扩展到其他痕量气体检测应用，包括生物医学呼吸诊断。其他应用在检测对健康、职业安全和全球变暖重要的其他环境物种方面比比皆是。该研究项目将产生比竞争技术更小，更便宜，更坚固的传感器。

This Small Business Innovation Research (SBIR) Phase I research project will determine the performance and operating specifications for an inexpensive laser spectrometer suitable for high-precision detection of carbon dioxide in the environment. Carbon dioxide is the major contributor to greenhouse gas build-up in the atmosphere and is effecting global climate change. It is important to measure small changes on the large atmospheric background concentration. The new sensor will be about the size of a can of soda and provide parts-per-billion (ppb) CO2 sensitivity in a few seconds. The fully developed rugged prototypes will be suitable for long-term detection of carbon dioxide in environmental field applications. The significantly improved price point will enable widespread distribution of these sensors for atmospheric measurement applications without sacrificing performance for price.This will enable more widely distributed measurements of anthropogenic greenhouse gases that are leading to global climate change. The basic technology shall extend to other trace gas detection applications including biomedical breath diagnosis. Additional applications abound in detection of other environmental species important to health, occupational safety, and global warming. This research project will result in sensors that are smaller, less expensive, and more rugged than competing technologies.
