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.
偏光显微镜在液晶及其他软材料科学领域带来了诸多进展，包括那些具有生物起源的材料。光学和基于计算机分析的最新发展催生了新一代定量偏光显微镜，它能够生成光轴的空间分布图。不幸的是，大多数现有方法需要长时间采集多张图像，然后对这些图像进行分析以生成分布图。我们描述了一种多色偏光显微镜，它能够在单次曝光中绘制光轴图案，从而实现快速的时间分辨率。我们将这种新型显微镜与传统偏光光学显微镜和Hinds Instruments公司的MicroImager等替代技术进行了对比分析。
