摘要： The polarization angle θ1 of a polarizer (14) is set, and the reflection intensity S1 in a cross Nicol state and the reference reflection intensity Ref1 of a liquid crystal cell (15) are measured. A different polarization angle θ2 is then set, and the reflection intensity S2 in a cross Nicol state and the reference reflection intensity Ref2 of the liquid crystal cell are measured. The rations S1/Ref1, S2/Ref2 of measured intensities and the ratio S1 · Ref2/S2 · Ref1 is determined in order to cancel the background components of the reference reflection intensities Ref1, Ref2 thus determining the value of cell gap accurately (Fig. 1).

摘要： The polarization angle υ1 of a polarizer (14) is set, and the reflection intensity S1 in a cross Nicol state and the reference reflection intensity Ref1 of a liquid crystal cell (15) are measured. A different polarization angle υ2 is then set, and the reflection intensity S2 in a cross Nicol state and the reference reflection intensity Ref2 of the liquid crystal cell are measured. The ratios S1/Ref1, S2/Ref2 of measured intensities and the ratio S1•Ref2/S2•Ref1 is determined in order to cancel the background components of the reference reflection intensities Ref1, Ref2 thus determining the value of cell gap accurately (figure 1).
