In single exposure off-axis interferometry, multiple information can be recorded by spatial frequency multiplexing. We
investigate optimum conditions for designing 2D sampling schemes to record larger field of view in off-axis
interferometry multiplexing. The spatial resolution of the recorded image is related to the numerical aperture of the
system and sensor pixel size. The spatial resolution should preserve by avoiding crosstalk in the frequency domain.
Furthermore, the field of view depends on the sensor size and magnification of the imaging system. In order to preserve
resolution and have a larger field of view, the frequency domain should be designed correctly. The experimental results
demonstrate that selecting the wrong geometrical scheme in frequency domain decrease the recorded image area.
