New ultrasound techniques for peering inside bony structures

Ultrasound—sound with frequencies higher than those audible to humans—is commonly used in diagnostic imaging of the body's soft tissues, including muscles, joints, tendons and internal organs. A technology called high-intensity ...

Ultra-thin camera creates images without lenses

Traditional cameras—even those on the thinnest of cell phones—cannot be truly flat due to their optics: lenses that require a certain shape and size in order to function. At Caltech, engineers have developed a new camera ...

SAVI camera ditches long lens for distant images

A unique camera that can capture a detailed micron-resolution image from a distance uses a laser and techniques that borrow from holography, microscopy and "Matrix"-style bullet time.

Engineers develop novel lens for super-resolution imaging

A team of researchers from the National University of Singapore's Faculty of Engineering has developed a novel lens for super-resolution imaging which breaks resolution limitations in microscopy and has potential applications ...
