Temporal multiplexing by SimVis, new publication in Biomedical Optics Express
The SimVis technology to simulate multifocal corrections relies on fast tunable lenses (temporal multiplexing). We propose a method to generate and evaluate the temporal profile describing real multifocal lenses (segmented refractive, trifocal diffractive and extended depth of focus) based on the fitting of the through-focus (TF) optical quality of the multifocal component of a given multifocal lens to a linear combination of TF optical quality of monofocal lenses viable with a tunable lens. Visual Strehl ratio and TF simulated images obtained with estimated time coefficients closely matched those predicted with the M-IOL. The study also investigates the effects of temporal sampling, varying pupil size, monochromatic aberrations, longitudinal chromatic aberrations and temporal dynamics on SimVis.
