Detection of CPU temperature distribution using optical computerized tomography

摘要

In this paper, we present Optical Computerized Tomography (OCT) technique to reconstruct the 3D temperature field generated by Center Processing Unit under working condition. Since the temperature field leads to the change of the refractive index distribution, we can obtain the temperature distribution from refractive index distribution through thermodynamics equations. The interferometry projection of wavefront is captured instantly by Charge Coupled Device using rotary interferometer. The rotary interferometer is firstly used in the reconstruction of stable temperature field. Multi-direction interferometry projections are obtained easily with rotary interferometer. Algebra Reconstruction Technique is used to reconstruct the projection data, and the results calculated with different grids are presented.
