Abstract

A measurement system comprises near-infrared semiconductor diodes operating in pulsed mode and a detection system comprising a camera configured to be synchronized to the diodes and to capture light reflected from bodily tissue. The measurement system may also comprise a time-of-flight sensor or a beam splitter to separate the diode light into a plurality of spatially separated lights. The measurement system including a processor is further coupled to a chemical detection system comprising a thermal or lamp based infrared light source and a multi-path spectroscopy system, comprising a first arm performing spectroscopy on a first gas and a second arm performing spectroscopy on a second gas. The processor is configured to process the image from the camera system and the information from the spectroscopy system. The first gas may comprise carbon dioxide, while the second gas may comprise hydrocarbons. The measurement system may be mounted in a vehicle.
