ABSTRACT:
A non-periodic reflection beamsplitter or reflector for use in an interferometer. The interferometer employs non-periodic reflectors or a non-periodic beamsplitter in order to produce interference patterns to analyze. The non-periodic reflectors or beamsplitters may be concentrically arranged reflectors having equal area. The beamsplitter consists of two adjacent non-periodic structures having complementary reflection and transmission patterns.
