The digital method of surface reflectance coefficient measurement

Abstract

The connection between the reflectance of a surface and the coordinate of picture in a photodetector plane is established. The digital method of measurement of reflectance with application of the multielement photodetector is developed. This method allows to increase accuracy of measurements to the tenth shares of percent.
