摘要： A liquid crystal optical performance monitor is described that employs a liquid crystal tunable filter for receiving a P-polarization beam and a rotated S-polarization beam from a C-polarizer. The rotated S-polarization beam from a birefringent crystal in C-polarizer propagates through a waveplate which rotates the polarization by 90 degrees, resulting in the rotated S-polarization beam having the same polarization orientation as the P-polarization beam. The liquid crystal tunable filter therefore receives just the P-polarization orientation. The C-polarizer and a small beam collimator are rotated so that the polarization orientation of the P-polarization beam and the rotated S-polarization beam matches the orientation of the LC inside the LC cavity of the LC tunable filter. In a first embodiment, the liquid crystal optical performance monitor is implemented with a photodiode. In a second embodiment, the liquid crystal optical performance monitor is implemented with a bi-cell photo diode.
摘要翻译：描述了一种液晶光学性能监视器，其使用液晶可调滤波器来接收P偏振光束和来自C偏振器的旋转的S偏振光束。来自C偏振片中的双折射晶体的旋转S偏振光束通过使偏振旋转90度的波片传播，导致旋转的S偏振光束具有与P偏振光束相同的偏振取向。因此，液晶可调滤波器仅接收P偏振取向。 C偏振器和小光束准直器被旋转，使得P偏振光束和旋转的S偏振光束的偏振方向与LC可调谐滤光器的LC腔内LC的取向一致。在第一实施例中，液晶光学性能监视器由光电二极管实现。在第二实施例中，液晶光学性能监视器由双电池光电二极管实现。

摘要： A polarization controller includes: a liquid crystal cell; a mechanism for determining a compensation voltage; and a voltage driving circuit for applying the compensation voltage to the liquid crystal cell, where the application of the compensation voltage optimizes an extinction ratio of the liquid crystal cell. The controller controls the extinction ratio using an applied voltage to compensate for temperature changes, liquid crystal cell gap variations, and other errors of the liquid crystal cell. This controller is aimed at liquid crystal devices used in a wide ambient temperature range and is also useful to compensate for the fabrication errors of the liquid crystal switches.
