Polarized laser light microscopy is used to investigate single isolated wood fibers. The macerated Scots pine (Pinus sylvestris L.) fibers are fixed for laser-optical and x-ray experiments perpendicularly on sawn slits of glass support plates. In the optical experiments, the fibers are fixed under a laser microscope and the electric field vector is rotated together with a linear polarizing plate. The images of the fibers, taken through our polarizing microscope, are grabbed consecutively with a charge-coupled device (CCD) camera, and they are recorded in the memory of a PC for analysis. The calculated values of microfibril angles from the responses of the laser polarimetry data correlate to the orientation of the microfibril angles.
