High longitudinal selectivity of the shifting multiplexing with spherical reference wave is proposed and demonstrated. A simpliΓΏed method based on wave optics is used for calculating the selectivity, and the result ΓΏts well the experimental measurement. Under the paraxial condition, a simple formula
