METHOD FOR FOCUSING OF WAVE FIELD, DEVICE FOR ITS REALISATION AND METHOD FOR PREPARATION OF ORDERED SET OF FOCUSING ELEMENTS FOR FOCUSING DEVICE Russian patent published in 2009 - IPC G02B27/16

Abstract RU 2352970 C1

FIELD: physics, optics.

SUBSTANCE: suggested invention is related to method and device for wave field focusing with the help of focusing elements set. Specified elements are arranged in the form of plates having mirror coating. At that mentioned plates are installed in focusing device circularly with gap between each other, symmetrically in relation to central axis of symmetry, and bent in certain manner to provide for required angles of beams deviation.

EFFECT: increased total aperture, optimisation of focusing properties of optical system.
