Indoor air pollution and the contribution of biosensors

elliptical mirrors optimized for the optical path and light intensity is an example of an optical-based sensor ( 98 ). It has two distinct features: one is focusing infrared (IR) light onto the detector with a minimum cavity volume and the other is an increased optical path length to enhance the sensitivity and accuracy. Other optical approaches are based on changes in the sensing membranes reflective indeces, induced by the presence of the toxicants in the air. These sensing materials may be used as dyes ( 99 ), crystals ( 100 ) or as a thin film placed on the prisms
