A new phase-shifting technique is developed for a Jamin interferometer used in refractive index measurement. Only one wave plate is added to the original interferometer. Theoretical analysis is performed to derive the phase shifting algorithm. This technique overcomes the difficulty of limited space for installing a phase shifter in the interferometer. The test result demonstrates the effectiveness of this method.
