    • A polarizing plate 4 is disposed to polarize light parallel to the X axis of liquid crystal display 3, which may be optionally rotated to a position where the intensity of a light that transmits the liquid crystal display 3 takes an extreme value (maximum or minimum) and an output Ix using a photodetector 6 is measured. The polarizing plate 4 is then disposed to polarize light parallel to the Y axis to thereby measure an output Iy using the photodetector 6. The polarizing plate 4 is then disposed to polarize the light in the direction inclined by 45 degrees between the X and Y axes to thereby measure an output I45 using the photodetector 6. A quarter wavelength plate 5 optionally may be disposed between the polarizing plate 4 and the liquid display 3 such that its axial direction is inclined by 45 degrees from the polarizing direction of the polarizing plate 4 while disposing the polarizing plate 4 so as to polarize light at 45 degrees from both the X and Y axes. In this position, an output Iq45 is measured by the photodetector. Stokes parameters are calculated according to each of the measured values Ix, Iy, I45 and Iq45, and according to the calculated Stokes parameters, the thickness of the liquid crystal layer and/or the twist angle of liquid crystal molecules of the liquid crystal display 3 can be determined. Optionally, the light intensities may be measured by a two-dimensional photodetector and Stokes parameters for a plurality of points on the liquid crystal display may be simultaneously or substantially simultaneously determined.
    • 偏振板4被设置为使平行于液晶显示器3的X轴的光偏振,该液晶显示器3可以可选地旋转到使液晶显示器3透射的光的强度达到极限值(最大值或最小值)的位置, 并且测量使用光电检测器6的输出Ix。 然后将偏振板4设置成使平行于Y轴的光偏振,从而使用光电检测器6测量输出Iy。然后,偏振板4被设置为使光沿X轴和Y轴之间倾斜45度的方向偏振 从而测量使用光电检测器6的输出I45。四分之一波长板5可选地可以设置在偏振板4和液体显示器3之间,使其轴向方向从偏振板4的偏振方向倾斜45度,同时 设置偏振板4以使从X轴和Y轴两个角度偏离45度的光。 在该位置,由光电检测器测量输出Iq45。 根据测量值Ix,Iy,I45和Iq45中的每一个计算斯托克斯参数,并且根据计算的斯托克斯参数,液晶显示器3的液晶层的液晶层厚度和/或液晶分子的扭曲角度 可以确定。 可选地,光强度可以通过二维光电检测器测量,并且可以同时或基本上同时确定液晶显示器上的多个点的斯托克斯参数。

    • An apparatus for processing and packaging a photographic film has a film supply unit for unreeling and cutting off a film roll of an elongate photographic film, and supplying a sized film, a film winding unit for winding the sized film around a spool thereby to produce a roll, a cartridge production unit for crimping a cap on an end of a rounded barrel plate thereby to produce a one-end-open cartridge, an assembling unit for inserting the roll into the one-end-open cartridge and thereafter crimping a cap on an opposite open end of the one-end-open cartridge thereby to produce a film-contained cartridge, and an encasing unit for placing the film-contained cartridge into a case and attaching a case cap to an open end of the case thereby to produce a packaged product. The film supply unit, the film winding unit, and the assembling unit are accommodated altogether in a dark chamber. The apparatus is relatively simple in overall arrangement, and allow various types of operation to be carried out easily and efficiently.
