一种确定反射型液晶（LC）单元的单元厚度的光学测量方法，其使用偏振转换装置（例如，圆形均匀对准的LC（CH-LC）单元）和电荷耦合装置（CCD）照相机来制备。由于通过CH-LC盒在真实的时间中测量来自反射LC盒的空间光强度分布的最小点，然后可以通过琼斯矩阵分析来导出盒厚度。这种方法的优点是，电池厚度的测量不受来自玻璃基板的表面和界面的反射分量的影响。
An optical measurement method to determine the cell thickness of reflective liquid crystal (LC) cells is prepared using a polarization-converting device such as a circularly-homogeneously aligned LC (CH-LC) cell and a charge couple device (CCD) camera. Since the minimum point of the spatial light intensity distribution from the reflective LC cell is measured in real time through the CH-LC cell, and then the cell thickness can be derived by the Jones matrix analysis. This method has an advantage that the measurement of the cell thickness is not affected by the reflection component from the surface and interface of glass substrates.
