Abstract:
Methods and systems are provided to measure the optical anisotropy properties of a film on glass or other substrates. This technique is suitable for production environments, and is not strongly affected by the TFT or CF active area on LCD panels, even for very high pixel density displays. A method is provided for measuring a magnitude and orientation of optical anisotropy. These methods and systems include an optical anisotropy measurement apparatus for measuring anisotropic materials in a reflection or transmission configuration. The methods and systems may measure a Mueller matrix, diattentuation orientation, or retardance of a sample at one or more rotation angles to calculate anisotropic magnitude and orientation.
