Liquid crystal filter system with a high precision for night vision is comprised of a wideband optical filter having a criticalwavelength, and a liquid crystal notch filter.
高精度夜视液晶滤光系统包括一个具有临界波长的宽带光学滤光器和一个液晶陷波滤光器。

Three variables are considered: critical buckling position, and neutral plane, the fiber buckling half-wavelength.
引入三个变量：临界屈曲位置、中性面位置和纤维屈曲半波长。

The results show that there are inverse proportional relationship between full wavelength at half maximum(FWHM)of the LIV signal and critical sample rate of data acquisition card.
