A method based on digital holographic interferometry for measuring the mutual diffusion coefficients of binary liquid is introduced. With uncertainty analysis and experimental verification, the uncertainties of temperature and mutual diffusion coefficient are estimated to be no greater than +- 0.16 K and +- 0.2 %, respectively. On this basis, the mutual diffusion coefficients for diethyl carbonate and diethyl adipate in heptane were measured from T = (278.15 to 338.15) K under atmospheric pressure, and a polynomial was fitted by the experimental data.
