论文摘要
偏振显微镜在液晶和其他软材料（包括生物学起源的材料）科学方面带来了许多进步。光学和基于计算机的分析的最新发展使新一代的定量偏振显微镜产生了视轴的空间图。不幸的是，大多数可用的方法都需要长时间的多个图像的收购时间，然后分析这些图像以生成地图。我们描述了一个多色偏振显微镜，该显微镜可以在单发曝光中绘制光轴的模式，从而实现快速的时间分辨率。我们对新显微镜进行了比较分析，并使用诸如HINDS仪器的常规偏振光学显微镜和微模构架等替代技术进行了比较。
Polarizing microscopy brought about many advancements in the science of liquid crystals and other soft materials, including those of biological origin. Recent developments in optics and computer-based analysis enabled a new generation of quantitative polarizing microscopy which produces spatial maps of the optic axis. Unfortunately, most of the available approaches require a long acquisition time of multiple images which are then analyzed to produce the map. We describe a polychromatic polarizing microscope, which allows one to map the patterns of the optical axis in a single-shot exposure, thus enabling a fast temporal resolution. We present a comparative analysis of the new microscope with alternative techniques such as a conventional polarizing optical microscope and MicroImager of Hinds Instruments.
