Abstract:This paper presents a novel uncertainty optimization algorithm for the design of line-of-sight systems used in tomographic inversion. By extending Gaussian process tomography from discrete pixel space to continuous function space through Bayesian inference, we introduce an uncertainty function and analyze its typical distributions. We develop an algorithm to minimize the uncertainty, which is then applied to optimize the line-of-sight configuration of the internal camera in the ITER project. Uncertainty analys… Show more
