My guess is that you would write a computer program to generate a large
original and then photo-reduce it i
the difficulty involved in making a photon sieve is about the same as making
a polarizing filter

I notice that the caption describes a photon seive as containing
"tens of thousands of pinholes." This does not sound like a very
easy device to produce.

This looks very interesting.
Does anyone know anything more about it?
Is it available?
Has anyone tried it?

There may be a new kind of zone plate called the 'photon sieve'. Instead of
using clear and opaque concentric rings, it uses pinholes of decreasing diameter
arranged in rings related to the zone plate.
