标题： The use of light polarization for weak-lensing inversions

摘要： 弱引力透镜星系的综合光学偏振测量可以为透镜模型提供重要的约束。 所概述的方法依赖于这样一个事实，即光学偏振方向的取向不会受到弱引力透镜的影响。 成像星系的半长轴与综合光学偏振方向之间的角度因此可以说明由引力透镜产生的畸变。 尽管该方法依赖于暗弱星系的偏振测量，但大型望远镜和改进的技术应在不久的将来使这些测量成为可能。 显示英文摘要

摘要： The measurement of the integrated optical polarization of weakly gravitationally lensed galaxies can provide considerable constraints on lens models. The method outlined depends on fact that the orientation of the direction of optical polarization is not affected by weak gravitational lensing. The angle between the semi-major axis of the imaged galaxy and the direction of integrated optical polarization thus informs one of the distortion produced by the gravitational lensing. Although the method depends on the polarimetric measurement of faint galaxies, large telescopes and improved techniques should make such measurements possible in the near future.
