Ultra-thin film creates vivid 3D images with large field of view

Researchers have developed a new ultra-thin film that can create detailed 3D images viewable under normal illumination without any special reading devices. The images appear to float on top of the film and exhibit smooth ...

Vision changes in space

Understanding the effects of microgravity on the human body is essential in enabling astronauts to travel through the harsh environment of space for months, or even years. Significant changes to the body's skeletal and muscle ...

Optical imaging

Optical imaging is an imaging technique.

Optics usually describes the behavior of visible, ultraviolet, and infrared light used in imaging.

Because light is an electromagnetic wave, similar phenomena occur in X-rays, microwaves, radio waves. Chemical imaging or molecular imaging involves inference from the deflection of light emitted from (e.g. laser, infrared) source to structure, texture,anatomic and chemical properties of material (e.g. cristal, cell tissue). Optical imaging systems may be divided into diffusive and ballistic imaging systems.
