Backscattering of polarized laser radiation by thermalcontrol coatings and constructional materials

The backscattering of spacecraft materials and coatings illuminated by linearly polarized radiation of He-Ne laser at a wavelength of 632.8 nm has been studied. Bistatic measurement scheme was used, i. e. the laser and a detector were placed stationary. Variation of the incidence angle was carried out by sample rotation. There was a good agreement between the results of measurements and calculations.
