Nonlinear Bayesian Doppler Tomography for Simultaneous Reconstruction of Flow and Temperature
Kenji Ueda, Masaki. Nishiura
We present a nonlinear Bayesian tomographic framework for Doppler spectral imaging that enables simultaneous reconstruction of emissivity, ion temperature, and flow velocity from l…

Nonlinear Gaussian process tomography with imposed non-negativity constraints on physical quantities for plasma diagnostics
Kenji Ueda, Masaki Nishiura
We propose a novel tomographic method, nonlinear Gaussian process tomography (nonlinear GPT), that uses the Laplace approximation to impose constraints on non-negative physical qua…
