A prototype system for plasma turbulence tomography was tested in linear plasma with aiming at future application to toroidal plasma. The line-integrated plasma emission lines of ArI and ArII were measured with sufficiently high signal-to-noise ratios, and the signals were reconstructed using the maximum likelihood expectation maximization (MLEM) algorithm and parallel computing. Here, the first results for local plasma emissions and fluctuation spectra obtained with the prototype system are reported.
