The measurement of 3-D asymmetric temperature field by using real time laser interferometric

摘要

A real time nondestructive temperature measurement technique based on laser holographic interference tomography techniques is presented. An He-Ne laser is used as light source, and a CCD video camera is used to grab the interferogram. This laser holographic tomography Techniques is applied to the measurement of the temperature fields generated by tow heated Rods. Since data error is inevitable in engineering measurement, it is necessary to study the Reconstruction techniques for reconstructing the temperature field.
