We develop an efficient methodology to extract the tomographic BAO information from galaxy survey based on the optimal redshift weighting scheme, and perform anisotropic BAO measurements in Fourier space using the eBOSS DR14 quasar catalog. We reconstruct the evolution history of the BAO distance indicators in the redshift range of 0.8<z<2.2 and improve the constraint on the BAO dilation parameter \alpha(zeff).

王丹丹：Dandan Wang obtained her Bachelor of Science in Yunnan University, and continues her Ph.D in NAOC. She worked as a member of eBOSS and DESI. She developed an efficient method to extract evolution information from tomographic BAO and RSD measurements. Her work was published as one of the serial papers of eBOSS work group.
