We theoretically investigate atom interferometric schemes based on three Kapitza–Dirac pulses in a one-dimensional harmonic trap. Kapitza–Dirac pulses as beam splitters create several spatially addressable modes with different momentum. The one-dimensional harmonic potential well acts as a mirror in an optical interferometer, which causes different modes to interfere and numerous high-contrast fringes appear in each mode at the time of measurement. The sensitivity of this atom interferometer in measuring gravitational acceleration can reach , which is further improved with increasing the number of modes.
