Bidiectional reflectance changes induced by blue light in Arabidopsis - two polarizer setup

Time courses of the polarized red-light bidirectional reflectance induced by 1 h irradiation with high blue light (100 µmol·m^-2·s^-1) of the adaxial surface of rosette leaves of 5-week-old wild-type and <i>phot1phot2</i> <i>Arabidopsis</i> plants. The blue actinic and red measuring beams impinged the adaxial leaf surface at the angle of 55°. For measurements of diffuse reflectance, the detector was positioned at 0° to the leaf’s normal. For measurements of combined specular and diffuse reflectance, the detector was positioned at -55°. Four possible combinations of the orientation (<i>P/S</i>) of the polarizers in front of the measuring light source and the detector were examinedBinary files can be opened with BeamJ (https://github.com/pawelHerm/beamJ/tree/master/BeamJ), while the CSV files can be opened with a text editor or MS Excel
