We report on unwanted effects of pixel cross-talk and its mitigation on the experimental realization
of the double-phase method with phase-only spatial light modulators. We experimentally demonstrate that a
generalized sampling scheme can reduce nonuniform phase modulation due to the pixel cross-talk phenomenon
and, consequently, improve the quality of amplitude and phase images obtained with this encoding method.
To corroborate our proposal, several experiments to reconstruct amplitude-only as well as fully independent
amplitude and phase patterns under different spatial sampling schemes were carried out. We also show how
a convenient implementation of the well-known polarization-based phase-shifting technique can be employed to
measure the encoded complex field using only a conventional CMOS camera. [-]
