Experimental evaluation of Fourier transform holograms by a self-interferometric technique [PDF]
EPJ Web of Conferences, 2022 We present a technique that combines an encoding method to display complex-valued holograms onto a phase-only spatial light modulator (SLM) with a phase-shifting interferometric (PSI) technique for experimentally evaluating the generated complex-valued ...

Optical Behavior of an Enhanced Monofocal Intraocular Lens Compared with a Standard One
Applied Sciences, 2023 The aim of this work was to compare an enhanced monofocal (RayOne EMV RAO200E, Rayner) and standard monofocal (RayOne RAO600C Aspheric, Rayner) intraocular lenses (IOLs) for three nominal powers (+10.00 D, +20.00 D and +30.00 D) as a function of the ...
