  The article presents the experimental measurements of the amplitude of the
moir\'e patterns in a digital autostereoscopic barrier-type 3D display across a
wide angular range with a small increment. The period and orientation of the
moir\'e patterns were also measured as functions of the angle. Simultaneous
branches are observed and analyzed. The theoretical interpretation is also
given. The results can help preventing or minimizing the moir\'e effect in
displays.
