Vector diffractive optical element as a full-Stokes analyzer

Generating multiple polarization outputs using random binary patterns with cascaded spatial light modulators

“…We divide the output plane into eight angular sectors and a delta function is placed at the center of each sector, forming a circular output pattern with an arrangement similar to a recently proposed vectorial diffractive element. 19 To multiplex the eight patterns, we need to create an additional random binary (1,0) pattern Cðu; vÞ and its orthogonal version cðu; vÞ. Now we can form eight orthogonal random patterns as the products a 1 ¼ ABC, a 2 ¼ ABc, a 3 ¼ AbC, a 4 ¼ Abc, a 5 ¼ aBC, a 6 ¼ aBc, a 7 ¼ abC, and a 8 ¼ abc.…”
