Strobe lighting more "accurate"?

Came across this article discussing using strobe lights for tin plate photographic preservation:

There was already a thread about using polarized glass for the platens.

Is this accurate? Has anyone looked at using strobes to more "accurately" light book pages?The LED in the scanner that illuminates artwork emits diffused ("soft") light... Diffused light also has the tendency to flatten out the overall tonal range of an original that may not be visible to the naked eye... I use strobe lights to illuminate the artwork. Strobes produce "hard" light, much like the sun on a clear day. In addition to the strobes, I place a polarizer over the camera lens and polarizer gels over the strobe lights. This eliminates all reflections and enables the camera to pick up a greater tonal range along with more detail.
