The Rabi regime for a Bose-Einstein condensate (BEC) in double-well potential occurring for sufficiently strong cross-collision strengths is analyzed. It is shown that in this regime the potential barrier acts as a temporal atomic beam splitter. An ideal 50:50 atomic beam splitter reached at specific intervals of time is employed for a balanced homodyne detection of the condensate relative phase.
