The uncertainty principle in classical optics

Research output: Contribution to specialist publicationArticle

5 Scopus citations


The constraints imposed by the uncertainity principle on classical optics problems was discussed. The separation of two overlapping beams of identical wavelength having slightly different propagation directions and the limits of separating co-propagating beams having slightly different wavelengths was analyzed. It was found that the two constituent composite beams continue to overlap at first, giving rise to interesting interference patterns. After a sufficient propagation distance, the beams separate and go their own ways.
