CA 2440992

The invention provides an ultra-high numerical aperture imaging device (1) comprising two rotationally symmetric curved mirrors (11b, 12b), which can be used to achieve very high concentrations of light or other sorts of wave (or other sorts of physical entities that satisfy equivalent "ballistic" equations of motion) or can be used in reverse to form a beam that has a small angle spread, and which can be combined with a further plane, partially transparent mirror (if necessary with additional components to attenuate and rotate the polarisation of the waves involved), to create a device able to achieve a materially better resolution than that implied by the traditional Rayleigh resolution criterion. A detailed method for designing such a device is also disclosed.

L'invention concerne un dispositif d'imagerie (1) à ultra-haute ouverture numérique, comprenant deux miroirs incurvés rotativement symétriques (11b, 12b), pouvant être utilisés pour obtenir des concentrations très élevées de lumière ou d'autres sortes d'onde (ou d'autres sortes d'entités physiques présentant des équations balistiques de mouvement équivalentes) ou pouvant être utilisé de manière inverse pour former un faisceau possédant un petit angle d'ouverture, et pouvant être combiné avec un miroir plat supplémentaire en partie transparent (si nécessaire avec des composantes supplémentaires pour atténuer et inverser la polarisation des ondes impliquées), afin de créer un dispositif permettant d'obtenir une résolution sensiblement meilleure que celle induite par les critères de résolution de Rayleigh. L'invention concerne également un procédé de fabrication détaillé de ce dispositif.
