    • Upper bound of signal-relevant efficiency of constrained diffractive elements 

      Verhoeven AD; Aagedal H; Wyrowski F; Turunen J (, 2016)
      We define the signal-relevant efficiency (SRE) of a diffractive optical element as a measure of the proportion of the incident field power that ends up in the desired output signal. An upper bound for SRE is determined in ...
