Lasers measure tailpipe emissions

摘要

The University of Manchester in the UK is commercialising a laser measuring device that can be mounted directly inside vehicles' exhaust to measure emissions as they are driven. Dr Philip Martin, co-founder of spin-out company TDL Sensors, said: "This is the first instance of a near-infrared diode laser sensor being used directly in the exhaust of a static internal combustion engine to measure emissions."
