Abstract:

	Future space missions place stringent requirements on materials used on space vehicles.
The spectral reflectance properties of materials are critically important for controlling
manufacturing processes and assessing effects of exposure to ground handling and
the space environment. Current instruments for measuring spectral reflectance are
high-resolution laboratory devices that apply to small samples. In many applications,
it is undesirable or impossible to remove a small sample for laboratory evaluation.
The objective of this project is to develop the conceptual and functional design
for a portable spectroreflectometer to measure spectral reflectance of extended surfaces.
This instrument will use a prism monochrometer and an integrating sphere to provide
total hemispherical reflectance measurements from 0.25 to 2.5 m. Configurations will
be developed for a hand-held unit for both ground and space use and for a remotely
operated unit suitable for use on orbit with a remote manipulator system. (Note:

Potential Commercial Application:

Potential Commercial Applications: This instrument could be applied in optical and
thermal surface process control; in-process monitoring; receiving and pre-flight
inspection; on-site evaluation of surfaces; materials R&D; and paint and surface
treatment development.
