Feasibility Study of Birefringence imaging with a tilting stage

继一个成功的项目学生之后，这是一个继续开发双折射成像显微镜的建议，其中包括一个倾斜工作台。双折射是样品中光学各向异性的一种重要而敏感的测量方法，在常规显微镜中，它通常只在显微镜载玻片上投射时才能观察到。通过增加倾斜台，原则上可以获得平面外的信息，从而获得完整的三维数据。由此产生的系统将有助于晶体材料的自动识别，特别是样品中纹理的确定，例如岩石学切片和混合相晶体中的纹理。因此，这个主题本质上是跨学科的，横跨结晶学、材料科学、地球科学和化学。

Following on from a successful project studentship this is a proposal to continue the development of a birefringence imaging microscope incorporating a tilting stage. The birefringence is an important and sensitive measure of optical anisotropy in a sample and in conventional microscopy it is usually only observed in projection onto a microscope slide. The addition of a tilting stage enables in principle information to be obtained out of the plane and hence to give full three-dimensional data. The resulting system will help towards automatic identification of crystalline materials and, of especial interest, the determination of texture in specimens, such as in petrological sections and in mixed phase crystals. As such this topic is interdisciplinary in nature, spanning crystallography, materials science, earth sciences and chemistry.
