摘要

提出了一种在无透镜傅里叶变换构型下，利用数字全息技术对水的层流自由对流进行温度测量的方法。在对流流场的边界层内测量温度。用这种方法测得的温度与热电偶测得的温度的偏差在2%以内。

Measurement of temperature field in steady laminar free convection flow using digital holography

A method to measure the temperature by visualizing the laminar free convection flow of water is presented by using digital holography in lensless Fourier transform configuration. Temperature is measured within the boundary layer of the convective flow field. The deviation in temperature measured by this method and from that of obtained by thermocouple is within 2%.
