Hi Harry, interesting thought...
The film camera isn't a pattern contributor toward Moire interference
patterns, but it does have a random granularity in the photo emulsion.
Could the 'freaky patterns' that are created by overlaying random dots,
linked below, qualify as your "sampling device" to produce interference,
as you mentioned below?

My amateur compulsion stumbled onto a Moire interference pattern of
Newton's rings simulated in POVRay ray-trace model do some profound
patterns in oversampling at the extreme. The interference patterns
between two grids were modeled at thousands to a millions of orders of
magnitude difference in scale. Amazing patterns are produced. I have
one posted on my home page (Please excuse: only found on my personal
Media Wiki): https://groupkos.com/dev
The Newton's rings, if shown to radical resolution in a computer model,
will interfere with the pixel grid --even when the interference grids
are radically separated in scale --> because the interference is
occurring in the computer model.
The most radical pattern effect is the pattern-acceleration. The
acceleration patterns of Newton's rings literally shifted the patterns
into earlier and later patterns on a timeline of shifting patterns.
The simple interference of a circle and a square (pixel) made /a lens to
patterns in the future of the time-line animation/ (not shown
particularly at the link above, unless you notice the larger dots wobble
in place over time).
The animation of one shrinking pattern of two-patterns interfering -when
viewed over the time-line of frames like a movie, has periodic
pulsations of lensing events. This can be seen in the animation at the
link above (some patience for the large GIF to download).
Could the time-line fractality of Moire-patterns be doing interesting
things in the heat of the sub-quantum energies to make them pulsate over
time (per the Fermi–Pasta–Ulam–Tsingou recurrence effect in discussion
on another thread)?
But at the quantum reality, what are the two periodic effects involved
with the interference? Or is the heat of quantum reality pulsing with
the interference of many dimensional grid works?

If a Moire pattern can be photographed using a film camera then there
are moire patterns which exist without a sampling device.

The Moire effect is the result of spatial undersampling an image,
and the Moire pattern is the aliasing. This is the reason that
Canon and many other camera manufacturers put an optical blurring
filter in front of the image sensor. The blurring filter is a
spatial lowpass filter to prevent the aliasing of spatial
frequencies above the sampling frequency / 2.
Sampling is fundamentally a nonlinear process and thus the beat
can occur. That it can show up visually in the eye testifies to
the sampling within the eye.
