Optical tomography technique for measurement of 3D asymmetric temperature field

A 3D phase object reconstruction is usually studied by using optical tomography. In this paper, the reconstruction for the 3D asymmetric temperature field is studied using the convolution backprojection algorithm by means of computer simulation. It proves that the algorithm is feasible and accurate. Based on the computer simulation, reconstruction of a 3D asymmetric temperature field is realized by using the algorithm to deal with speckle photography.
