Paper Abstract

Infrared satellite sensors must be recalibrated in orbit using blackbodies small and light enough to fit on spacecraft. Emissivities very close to one can be achieved by observing closed interiors along rays making multiple reflections off surfaces that are both highly absorbing and specularly reflective. We analyze the effect of slightly nonideal specularly reflective surfaces having a small but finite diffuse reflectivity, showing how it limits the performance of a three-reflection specular blackbody.
