ABSTRACT:
Two sets of two single blazed binary diffractive optical elements form a beam separation control apparatus for expanding two closely spaced parallel beams into two wider spaced parallel beams or for contracting two wider spaced parallel beams into two closely spaced parallel beams. Four sets of two single blazed binary diffractive optical elements form a beam separation control apparatus for separating two closely spaced parallel beams into two wider spaced parallel beams for possible modulation or other optical effect, then returning the two beams to be closely spaced and parallel. A set of two adjacent and opposite single blazed binary diffractive optical elements can form a beam splitting apparatus or a beam combining apparatus.
