RER-Net: Refractive Error Regression Network for Multi-Angle Eccentric Photorefraction Pupil Images

IEEE International Symposium on Biomedical Imaging
Refractive error can lead to permanent vision impairment and has become a critical factor to various ocular diseases. Multi-angle near-infrared (NIR) eccentric photorefraction pupil images provide rich refractive information, offering a feasible and ...

Rapid response of photorefraction in vanadium and magnesium co-doped lithium niobate

Journal of Physics D: Applied Physics, 2019
Vanadium and magnesium co-doped LiNbO3 (LN) crystals were grown, and their photorefractive properties were studied in the visible spectral region. At 488 nm the shortest response time of 80 ms was achieved for an LN crystal co-doped with 0.1 mol% V2O5 ...
