New Compact Laser System can detect Person’s Breath Constituents

Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) France have come up with a new development to detect constituents of a person’s breath. The constituents can be varied ranging from greenhouse gases, other gases, as well as molecules. The process involves tapping middle infrared light source for the needful. Physically, the new development is a compact system that resembles a tiny suitcase. In terms of constitution, the system is simple
