通过将光学膨胀测量的最佳实践与数值方法相结合，开发了一种高速、高精度的技术，以亚像素分辨率测量悬浮、无容器处理的样品的体积。无容器处理提供了研究高活性材料的能力，而没有污染影响热物理性质的可能性。悬浮是一种常用的技术，用于分离正在处理的样品。非接触式光学热物性测量是传统测量方法无法实现的。现代的数字记录图像需要先进的数值例程来恢复样本边缘的亚像素位置，进而产生高精度的测量。(c) 2005年美国物理研究所。
By combining the best practices in optical dilatometry with numerical methods, a high-speed and high-precision technique has been developed to measure the volume of levitated, containerlessly processed samples with subpixel resolution. Containerless processing provides the ability to study highly reactive materials without the possibility of contamination affecting thermophysical properties. Levitation is a common technique used to isolate a sample as it is being processed. Noncontact optical measurement of thermophysical properties is very important as traditional measuring methods cannot be used. Modern, digitally recorded images require advanced numerical routines to recover the subpixel locations of sample edges and, in turn, produce high-precision measurements.
