Shutter speed, along with aperture value, is one of the fundamental properties of exposure: ie, how much light your camera gets exposed to. A faster shutter speed helps freeze action, whereas a slower ...

Pinhole pupilloplasty is a simple and low-cost solution to restore vision in patients with highly aberrated corneas and can ...

Constructed by inventor Oskar Barnack and his team beginning in 1923, these “0-series” devices preceded the Leica I, the first serially-produced Leica camera that debuted in 1925.  What made this ...

For over a century, surgeons performing delicate procedures have relied on stereoscopic microscopes to gain a sense of depth. These tools mimic human vision by presenting slightly different images to ...

Apple is investigating new image sensor technology that promises up to 20 stops of dynamic range. Here’s what that actually ...

A blue eye, with a brown eyebrow, appears in the center of the composition. Two additional illustrated diagrams appear at bottom: one showing how inverted images on the retinas of eyes are brought ...

This eye movement camera was built by Henry Roger (1891-1982), a German biophysicist who moved to the United States in 1923, and later established a laboratory in Sandy Hook, Ct. Dr. Charles Robinson ...

To promote the widespread use of light-field computational cameras, downsizing of the system is essential. This paper presents an 8.5 mm × 8.5 mm × 6.0 mm tiny compound-eye camera module based on the ...

Human remains have been found in Rocky Mountain National Park near Alpine Ridge Trail, according to a release from the park.

Despite all the scientific progress we've made and the incredible explorations of our solar system we've carried out, space itself remains one giant mystery. From the potential for life to exist on ...

In this work, we present a novel method to intention recognition, based on electroencephalogram (EEG) and eye movement in human-computer interaction(HCI). The fusion of EEG and eye movement will allow ...
