Non-intrusive soot volume fraction and temperature distribution reconstruction scheme was proposed based on the approximations of flame emission transfer model according to tomographic principle. Radiative sensor number and arrangement specifications were determined by lease square QR matrix factorization algorithm. Simulations show that the maximum discrepancies of temperature and fraction reconstructions are 0.2% and 2.5% respectively when four 320-pixel line-scan charge-coupled device sensors were arranged non-symmetrically. According to the anti-noise capability assessments the signal-to-noise ratio of the detectors should be larger than 60 dB in order to get reasonable results when the proposed method is adopted.
