System could provide first method for filtering light waves based on direction Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive. But now, for the first time, MIT researchers have produced a system that allows light of any color to pass through...

Newly Developed Holographic Process Uses Image-stabilized X-ray Camera
2014-01-07 11:40:04

Helmholtz-Zentrum Berlin A team headed by Stefan Eisebitt has developed a new X-ray holography method that will enable snap-shots of dynamic processes at highest spatial resolution. The efficiency of the new method is based on a X-ray focusing optics being firmly fixed to the object to be imaged. While this approach initially provides a blurry image, this can be focused in the computer based on the hologram information. At the same time, the rigid connection between the object and the...

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...
