Obtaining spatial information from an extremely unresolved source.
نویسنده
چکیده
A means to extract spatial information from an extremely unresolved source of light using a single element detector is demonstrated by use of an optical vortex coronagraph. Applications may range from astronomy to microscopy. For example, the centroid and angular extent of an unresolved collection of incoherent point sources is revealed.

An unresolved X - ray source inside the supernova remnant RCW 86
We report on the discovery of an unresolved X-ray source inside the supernova remnant G315.4-2.3 (RCW 86). The source is located 7 to the Southwest of the geometrical centre and may be close to the actual explosion centre of the supernova, which makes this a candidate for the stellar remnant associated with RCW 86. However, the presence of a possible optical counterpart with V ∼ 14 at 3 from th...
متن کاملSpatial distribution and degree of heavy metal pollution in urban roadside dusts from Sanandaj, Iran
Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...
متن کاملFourier-transform spectral imaging: retrieval of source information from three-dimensional spatial coherence
A method is described for efficiently obtaining the comprehensive information of a polychromatic radiator. Under certain conditions both the spatial and spectral details of the radiative object can be recovered simultaneously from the three-dimensional spatial coherence function in the diffraction region. The recovery of object information is based on a Fourier-transform relationship derived fr...
متن کاملاستفاده از تبدیل PCA مکانی جهت ادغام تصاویر چند طیفی و تک رنگ
Obtaining of an image with high spectral and spatial resolution is the goal of image fusion. The PCA is a well-known pan-sharpening approach widely used for its efficiency and high spatial resolution. However, it can distort the spectral characteristics of the multispectral images. To avoid the weak points of the standard PCA technique, Spatial PCA transform has been proposed and the reasons of...
متن کاملPotential site selection in ecotourism planning using spatial decision support tool
Northern areas of Pakistan have blessed with extremely beautiful natural landscapes, waterfalls, glaciated mountains, biodiversity rich valleys and forests and have extraordinary potential for ecotourism. Study is designed to propose potential sites for ecotourism in Kohistan, which is a least developed but biodiversity rich area of Pakistan. Poor planning and mismanagement of tourism practice...
