Integrated single embedded processor based laser spectroscopic sensor

This is an ultra-compact laser based gas sensor with fully integrated hardware, software, and optics. This device can automatically adjust laser wavelength and optical output, convert sensor power, measure and control target parameters, and communicate and/or process the acquired data for analysis. This platform consists of a spectroscopic source, an optical absorption module, and a detection element with the associated control electronics hardware and software. Such a fully integrated system has not been realized before, as current systems are based on modular architectures comprising power supply, controllers, environmental transducers and processing software and hardware. These existing systems usually require human intervention and are not fully integrated, while the architecture proposed by the inventors allows a single embedded processor to control all the subsystems required for operation of the sensor.

Advantages The benefits created by this architecture are multiple:
• lower cost of the device (from ~$10,000 - $15,000 to $1,000 or less)
• lower electrical budget (efficiency can be increased by 85-97%, which would allow building a battery operated device)
• smaller footprint (from table size to handheld)

Potential Applications These features, in turn, make possible applications such as:
• portable medical breath analyzers
• long-life atmospheric sensor networks
• large scale automotive/industrial monitoring of combustion
• sensor based security applications.
