New Imaging System Could Help Diagnose Disease And Monitor Hazardous Substances
2013-10-02 10:36:48

The Optical Society For hundreds of years, optical devices like telescopes and microscopes have relied on solid lenses that slide up and down to magnify and to focus. To tune how much light is received, conventional devices use mechanical contraptions like the blades that form the adjustable aperture in cameras. To meet demands for ever smaller imaging systems, researchers are working to create entirely unconventional ways of focusing light. In pursuit of this vision, engineers from the...

Tiny Camera Gives Big Picture View Without Sacrificing High-resolution
2013-09-25 09:34:47

The Optical Society New system could be used to build a camera that pans and zooms with no moving parts To capture all the details of a crime scene, you might take many photos at close range. To get the whole scene at once, you could use a wide-angle or fisheye lens; but without an especially large lens you would be sacrificing the fine resolution that would help you catch that partial footprint you might otherwise have missed. Now a new type of miniature camera system promises to give...

Brett Smith for redOrbit.com – Your Universe Online Astronomers have developed groundbreaking optical techniques to bring distant stars into focus and this same technology is now being appropriated by eye care professionals to improve their analysis and corrective methods. According to a recently published review in the journal Optometry and Vision Science by Indiana University optometrist Larry N. Thibos, the concept of ‘wavefront optics’ is transforming how vision professionals...

New Lenses For Nanoscale Light Beams Are Tiny Liquid Bubbles
2013-08-09 12:43:10

Penn State Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, high-speed circuits and displays, according to Penn State researchers. To combine the speed of optical communication with the portability of electronic circuitry, researchers use nanoplasmonics -- devices that use short electromagnetic waves to modulate light...

A magnifying glass is a convex lens, usually mounted in a frame with a handle, which is used to produce a magnified image of an object. The glass works by creating a magnified virtual image of an object behind the lens. However, the distance between the lens and the object must be shorter than the focal length for the glass to work. If the distance is not correct then the image will appear small and inverted. Many magnifying glasses are mounted on a stand to insure the proper distance...

Parabolic Mirror -- A parabolic reflector or parabolic dish is a reflective device formed in the shape of a paraboloid of revolution. Parabolic reflectors can either collect or distribute energy such as light, sound, or radio waves. The parabolic reflector functions due to the geometric properties of the paraboloid shape: if the angle of incidence to the inner surface of the collector equals the angle of reflection, then any incoming ray that is parallel to the axis of the dish will be...
