Visual Discomfort and Depth-of-Field [PDF]

open access: yesi-Perception, 2013
Visual discomfort has been reported for certain visual stimuli and under particular viewing conditions, such as stereoscopic viewing. In stereoscopic viewing, visual discomfort can be caused by a conflict between accommodation and convergence cues that ...

Fourier depth of field [PDF]

open access: yesACM Transactions on Graphics, 2009
Optical systems used in photography and cinema produce depth-of-field effects, that is, variations of focus with depth. These effects are simulated in image synthesis by integrating incoming radiance at each pixel over the lense aperture. Unfortunately, aperture integration is extremely costly for defocused areas where the incoming radiance has high ...

Learning flat optics for extended depth of field microscopy imaging [PDF]

open access: yesNanophotonics, 2023
Conventional microscopy systems have limited depth of field, which often necessitates depth scanning techniques hindered by light scattering. Various techniques have been developed to address this challenge, but they have limited extended depth of field (

Fast Three-Dimensional Profilometry with Large Depth of Field [PDF]

open access: yesSensors
By applying a high projection rate, the binary defocusing technique can dramatically increase 3D imaging speed. However, existing methods are sensitive to the varied defocusing degree, and have limited depth of field (DoF).
