摘要:渥拉斯顿棱镜是由威廉.海德.渥拉斯顿发明的,它由两个方解石直角棱镜组成,通常用加拿大胶粘合,两棱镜的光轴相互垂直。渥拉斯顿棱镜能产生两束相互分开的、振动相互垂直的平面偏振光。两光束分开的角度有棱镜的切割角和光的波长决定。在了解了格兰泰勒棱镜和格兰付科棱镜透射光强的扰动之后,我们可以推想出光在通过渥拉斯顿棱镜之后也会产生透射光强的扰动,而且扰动因子的考虑将比泰勒和付科棱镜的更为复杂。因为渥拉斯顿棱镜前后两个部分的棱镜光轴互相垂直,最后会后两束出射光,这两束光的扰动因子必然不同。同时出射光不再垂直于出射端面,这也将影响透射光强。4823

Title Transmission intensity disturbance in Wollaston prism
Abstract
Wollaston prism is invented by William Head Wollaston.It consists of two rectangular prism,which is usually binded by Canada glue and whose optical axis are perpendicular to each other.Wollaston prism could generate two beams separated from each other,mutually perpendicular vibration of plane polarized light.The separation angle between two beams depend on the cutting angle of prism and the wavelength.After the basic grasp of transmission intensity disturbance of Glan Taylor and Glan Foucault prism,we could safely suppose that transmission intensity disturbance can also happen when light get through Wollaston prism,and the disturbance factor would be more complicated because the optical axis are perpendicular,then there would be two transmitted beams.Obviously,they have different disturbance factors.Meanwhile,the transmitted light is no longer perpendicular to the surface of the prism,which will absolutely affect the transmitted light intensity.
