Digital holographic microscopy provides an ideal tool for 3D tracking of microspheres while simultaneously allowing a full and accurate characterization of their main physical properties such as: radius and refractive index. We demonstrate that the combination of high resolution multipoint tracking and accurate optical sizing of tracers provides an ideal tool for precise multipoint viscosity measurements. We also report a detailed evaluation of the technique's accuracy and precision in relation to the primary sources of error.
数字全息显微镜为微球的三维跟踪提供了理想工具，同时还能全面、准确地表征其主要物理特性，如半径和折射率。我们证明，高分辨率多点跟踪与示踪剂的精确光学尺寸测量相结合，为精确的多点粘度测量提供了理想工具。我们还报告了该技术相对于主要误差源的准确性和精密度的详细评估。
