Method to detect optical characteristics of reflective object, especially liquid crystal cell, as function of angle; involves measuring intensity of reflection as function of illumination angle |
摘要 |
The method involves measuring the intensity of radiation modulated and reflected by the liquid crystal cell as a function of illumination angle. The illumination radiation is masked to produce a specular beam (23) on the illumination side. An Independent claim is included for an illumination device for implementing the method.
