Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

The 3D display device shows an image with depth information. Conventional 3D display devices based on binocular parallax can focus accurately only on the depth of a specific screen. Because the human ...

In photography, depth of field refers to how much of a three-dimensional space the camera can focus on at once. A shallow depth of field, for example, would keep the subject sharp but blur out much of ...

This supplement is a compendium of research conducted by Johnson & Johnson Surgical Vision, Irvine CA about the performance of a new purely refractive Extended Depth of Focus IOL, TECNIS PureSee™ IOL.

One of the most striking differences between your iPhone and a large camera like a DSLR is the way the two cameras focus and control depth of field. In a DSLR, depth of field is easy to manage by ...

Researchers from the University of Tartu Institute of Physics have developed a novel method for enhancing the quality of three-dimensional images by increasing the depth of focus in holograms fivefold ...

Needle-shaped laser beams (NBs) featuring a long and narrow localization of photons can potentially allow non-diffracting pulses with undistorted temporal profiles. Using this kind of pulse in ...

Please provide your email address to receive an email when new articles are posted on . A pinhole effect, achieved through surgery, pharmacologic agents, IOLs or inlays, can treat significant ...

Latest addition to Alcon’s intraocular lens (IOL) portfolio expands surgeons’ presbyopia-correcting IOL (PC-IOL) offerings Vivity X-WAVE technology delivers extended range of vision while maintaining ...
