In the commercial fusion reactors, to keep Tritium breeding rate, the number of port or openings must be limited. Therefore, heat flux estimation using infrared thermography might be not applicable. The divertor tile equipped with thermocouples is still promising. However, necessary number of thermocouples to reconstruct profile is open question. In this work, this problem was studied with LHD divertor tile data.
