Abstract
Planar polyimide light guides can be used for the optical detection of various vapor concentrations. Therefore the birefringence of the light guide is monitored as a function of the actual vapor pressure. Using this principal several vapor concentrations of n-heptane and n- octane have been determined. Similar dynamic behavior can be observed for both components only differing in time constants. Furthermore the detection of n-heptane in a mixture with iso- octane can be realized. The waveguide sensor shows a sensitivity only to n-heptane and not so iso-octane vapors. The determination of the n-heptane concentration is not affected by the presence of iso-octane.
