Optical image formation science and technology have a long and intertwined history.
This has led to a series of displaced technologies, each based on improved underlying science made possible by the former accepted technology.
Improvements to optical science have been made possible largely as a result of using the previous iteration of optical image formation science and technology.
None of the technologies displaced by reference distribution real image formation (RIF) is based on fundamental physics (science).
Currently, the Huygens-Fresnel principle is assumed (erroneously) to be fundamental to the image formation process.
When nothing stops it light is assumed to propagate as spherical waves that emanate from single point sources.
According to this view, Independent spherical waves combine to form composite waves, as illustrated in the accompanying figure (Source: Wikipedia).
The Huygens-Fresnel principle is not a law of physics.
REFERENCE DISTRIBUTION REAL IMAGE FORMATION
RIF is based on the fact that two separated illuminated points in the object are needed to form light waves that contribute to image formation.
This is in direct contrast to the Huygens-Fresnel principle where it is assumed that only one illuminated point is needed,
Reference Distribution Real Image Formation (RIF) is a result of a careful and unique application of fundamental physics.
