| 摘 要： | 温度的微小变化必然会引起空气折射率的微小变化,进而影响通过该区域光的相位。采用迈克耳孙干涉仪与数字全息技术相结合的技术方案,实现对温度场分布的测量。借助数字视频技术,该技术架构可直接推广用于测量透明介质的流场分布及变化过程,如气流或水流中的密度分布以及变化过程等。

| Abstract: | The tiny change of temperature changes the refractive index of air,and then leads to the phase change of light propogating through the area where the refractive index has changed.We measure the change of temperature field by using Michelson interferometer and digital holography method.Our technique combined with digital photography can be used to measure hydrofield distribution and changing process,for instance,the density distribution and changing process in airflow and water stream. |
