This paper focuses on a method to measure $T_{rm e}$ without knowing transmissivity using Thomson scattering diagnostic with a double-pass scattering configuration. Effect of installation errors about the scattering angle to accuracy in $T_{rm e}$ is discussed. Application of this method to measure anisotropic $T_{rm e}$ , i.e. $T_{rm e}$ about the parallel ( $T_{rm e ||}$ ) and perpendicular ( $T_{rm e perp}$ ) directions for the magnetic field, is proposed. Although large statistical errors are expected because of correspondences between the scattered spectra from the first and second pass, stable accuracy appears in the area with $T_{rm e perp}/T_{rm e ||} > 0.5$ in the core measurements of JT-60SA.
