Fiberoptic Formaldehyde Field Sensors for Industrial Environments: Capitalizing on Evanescent-Wave Spectroscopy

November 01, 2020

An inexpensive fiberoptic-based formaldehyde field sensor is described for monitoring low-levels of formaldehyde, a widespread indoor air pollutant, based on the principle of evanescent wave absorption of light. Sensor prototypes following that principle are being tested in two plywood board production plants.
