英文摘要 | the key to the concept of tunable wavefront coding lies in detachable phase masks. ojeda-castaneda et al. (progress in electronics research symposium proceedings, cambridge, usa, july 5-8, 2010) described a typical design in which two components with cosinusoidal phase variation operate together to make defocus sensitivity tunable. the present study proposes an improved design and makes three contributions: (1) a mathematical derivation based on the stationary phase method explains why the detachable phase mask of ojeda-castaneda et al tunes the defocus sensitivity. (2) the mathematical derivations show that the effective bandwidth wavefront coded imaging system is also tunable by making each component of the detachable phase mask move asymmetrically. an improved fisher information-based optimization procedure was also designed to ascertain the optimal mask parameters corresponding to specific bandwidth. (3) possible applications of the tunable bandwidth are demonstrated by simulated imaging. (c) 2014 elsevier b.v. all rights reserved. |
