Miniaturized terahertz radiation source

A miniaturized terahertz radiation source based on the Smith-Purcell effect is provided, in which, from a focused electron source, a high-energy bundle of electrons is transmitted at a defined distance over a reflection diffraction grating composed of transversely disposed grating rods, so that, in response to oscillating image charges, electromagnetic waves of one wavelength are emitted, the wavelength being adjustable as a function of the periodicity of the lines and of the electron velocity. The elements of the radiation source, such as field emitter (1), electrostatic lens (4), beam deflector (5), grating (7) of metal, and a second anode (8), are integrated on a semiconductor chip using additive nanolithographic methods. The field electron source is constructed to project, as a wire, out of the surface, using additive nanolithography, and is made of readily conductive material having stabilizing series resistance. The wire is constructed, using computer-controlled deposition lithography, in a straight or curved, free-standing design. In its surface area, the base material bears a conductor structure for the electrical terminals and connections (2), including controllable voltage sources (3) for supplying the field emitter tips (1), lens (4), and control electrodes (5, 8). The terahertz radiation source is designed to be a powerful component that is available in modular form and is usable in any spatial situation.

Apparatus and method for efficiently increasing the spatial resolution of images

A method increases the spatial resolution of a source image based on an auxiliary, co-registered image of a higher spatial resolution. Each of the source and auxiliary images includes a plurality of pixels with corresponding spectral intensities and the method includes reducing, identifying, deriving, subdividing and modifying steps. Multiple auxiliary images can be used with the method.
In the reducing step, a spatial resolution of the auxiliary image is reduced to a common resolution with the source image. Then in the identifying step, corresponding groups of pixels at the common resolution in the source and auxiliary images are identified. Then in the deriving step, a mapping function is derived which relates the rate of change of intensity of each group in the auxiliary image and the corresponding rate of change of intensity in the corresponding group in the source image to the intensity vector. This map can be conditioned on any number of auxiliary image planes.
In the subdividing step, each source pixel is subdivided. Then in the modifying step, the spectral intensity of each subdivided source pixel is modifying based on the map and the local intensity variations of the auxiliary image. This results in increasing the resolution of the source image.
