We investigate the photoinduced anisotropy of a photochromic material of pyrrylfulgide/PMMA films. It is proven that when the film is illuminated with a linear polarization light, an optical axis that has the same polarization as the excitation light could be induced in the film. A matrix of light spots with different polarizations is recorded on the pyrrylfulgide/PMMA film. When reading out with non-polarization light, the matrix of light spots shows no information of pattes. However, when reading out with different linear polarization lights, different pattes could be observed. The experiment confirms that the pyrrylfulgide/PMMA film could be used to record two different polarization pattes in a matrix of spots. This property may be applied in camouflage technology.
