As this method of imaging becomes better understood, it can offer the best solution for problems in fields as diverse as architecture, medicine and mechanical engineering.
The concept of the photon

It has its logical foundation in the quantum theory of radiation. But the “fuzzy‐ball” picture of a photon often leads to unnecessary difficulties.

Whether photomultipliers, photodiodes or photoconductors are “best” in a given case depends on signal frequency, on the kinds of noise present and on the coherence of the radiation.
