In this study, we have measured the IR polarization characteristics of several surfaces that are close to being Lambertian, such as flowers of sulfur and gold-coated sandpaper. The measurements were carried out by using a CO2 laser as the source of radiation and irradiating the sample with either s or p polarized radiation. A polarizer in front of the detector could be set in the s or p position. It was found that the more Lambertian the sample, the lower the degree of polarization produced by it. Quantitative results are presented for the degree of polarization of the scattered radiation for all the surfaces studied. The results are correlated with the measured 'slope' of the surfaces.
