Erratum: Liquid crystal lens set in augmented reality systems and virtual reality systems for rapidly varifocal images and vision correction (Optics Express (2022) 30:13 (22768-22778) DOI: 10.1364/OE.461378)

The authors in Ref. [1] would like to have an addendum to cite the Refs. [2–5] works from the N. A. Riza lab that are prior design and demonstrations of the high speed lens based on digital polarization switching optics in cascade with birefringent fixed and tunable optical beamforming elements, including its application for volumetric displays. These works starting in 1998 should have been cited in Ref [1]. as belonging to the first demonstration of such a digital control high speed polarization-based variable focus lens versus the Ref. [24] citation in Ref. [1]. Specifically, in Refs. [2,3], Three Dimensional (3-D) optical scanner designs for 3-D beamforming were proposed using a variety of polarization sensitive optics including ferroelectric liquid crystals, nematic liquid crystals, polymer dispersed liquid crystals, passive lens and tilt optics and anisotropic predesigned and/or electronically programmable optic elements. References [4,5] reported on first experimental demonstrations of this fast 3-D beamformer in operation, including fast digital control variable focus lensing, the approach later also demonstrated in Ref. [1] cited Refs. [24–30].
