Applied Nanophotonics, Liquid Crystals and Biomedical Optics

A tunable extended depth of field (EDOF) imaging is presented using temporal multiplexing and a low-cost eightring, annular liquid crystal spatial light modulator. By changing between different phase profiles in the pupil plane of a lens we perform several levels of EDOF. Using these levels as a "database" it is shown by temporal multiplexing how to decompose tunable levels of EDOF.
