I Do slits absorb photons at the edges?

  1. Apr 12, 2017 #1
    Xiao et al say the following here: https://arxiv.org/pdf/1703.03818.pdf
    Is this correct? I'm finding it hard to believe that there is a probability that some irreversible events will occur that would ultimately result in heating up the mask (screen with slits). I mean, we could always make the screen out of highly reflective material that would either reflect most photons back towards the source, or let some pass with a small amplitude of detection on the other side.

    But a reflective screen actually absorbing photons? With the absorption events clustured near the edges?

    There is no such thing as a perfectly reflecting material. Some of the photons will ultimately be absorbed. In any case, I'm not sure why this would matter here: reflected photons will also affect uoutput.
