Optical sensors of gas on the basis of semiconductor sources of infrared emission

Abstract

Various constructions of optic sensors of gas and gas analyzers on their basis with the use of low-powered semiconductor sources of infrared emission for wave-length of 2,5–5,0 mm made on basis of InGaAs/InAs and InAsSbP/InAs heterostructures are worked out. The experimental results demonstrating the ability of application of semiconductor sources of infrared emission in optic sensors for measuring of metan concentration (CH4) and carbon dioxide (CO2) are given. The availability of use of such sensors in the gas analysis equipment of new generation is shown.
