【摘要】 木文描述了激光束通过位相物体后,在空间形成的激光散斑的运动规律。利用这一规律可以直接测量位相物体中折射率梯度的变化及其透明流体的密度场与温度场。它为微电子器件冷却技术的实验研究提供了一种十分有效的测试手段。更多还原

【Abstract】 In this paper,the laws of laser speckle movement in space when the light beamspass through the phase object are described.By means of the laws,the variations of refractiveindex,as well as density gradient and temperature gradient in fluid flow can be measured directly.It is highly recommended for use in experimental investigations in electronic cooling.更多还原
