Abstract

A dual-waveband, fiber-optic/infrared (F-O/IR) temperature measurement system was enhanced with incorporated optical chopping and applied to measure the surface temperature of a coated (aluminized) Kapton HN sample. The F-O/IR system provides a non-contact means for accurate membrane temperature measurement without distorting surface contour. An FTIR spectrometer was used to measure the absorptance and reflectance properties of the Kapton HN sample. A long-wave IR scanner was used to validate and enhance results obtained from the spectrometer and predict temperature dependence of optical properties. Data are presented that demonstrate the feasibility to apply the F-O/IR system for non-contact temperature measurement of highly reflective surfaces at low temperatures.
