Fig. 1. Principle of complex field modulation (CFM) using binary phase-engraved (BiPE) superpixels. a System schematic. BS1 and BS2, beamsplitters; L1 and L2, lenses; M1–M3, mirrors; PLM, phase light modulator. b Side-profile illustration of a one-dimensional (1D) BiPE superpixel of size m = 4 . c Exploded view of the structure of each PLM micromirror. d Illustration of the phase pre-factor created at the PLM surface, with boundary phase values and the footprints of superpixels and individual micromirrors highlighted. e Normalized micromirror displacement response illustrated as a function of electrode state (left) and as a distribution of displacement levels (right), adapted from data reported in Proc. SPIE 11698, 116980O (2021).
