then there won't be a photon to detect later.


even if you were using a single photon and you did not detect
the light that radiates away from the single photon
as the radiated light enters the 20 mediums and passes
through the 20 mediums with increasing thicknesses and exits
the 20 mediums over 20 different time periods and is absorbed
by the 20 photo cells and is collected and stored in the 20 capacitors, each of the 20 capicitors should register a charge.

so according to what you posted as soon as the light is
detected by the first photo cell the light that is trapped
inside the other 20 glass mediums will simply vanish?

is that your view on this?

3/4 inch of dust build up on the moon in 4.527 billion years,LOL and QM is fantasy science.
