Abstract

Optical interferometric high stability fields produced by laser beam are proposed to be used as an optical coordinate system. To produce such interferometric field over the large surface a set of optical elements and systems are proposed which consist of surfaces formed by means of off-axis rotation of parabola, ellipse or hyperbola and their confocal combinations (one of two focuses of each curve is common). If the source is situated at one of focuses (but not at the common one) such systems are completely free of backward reflected beam and aberrations. These systems allow one to reach the extremely small beam divergence and, hence, to get the extremely small focal spot. It is very important in some special applications. Such elements can be also independently used in laser optics, adaptive optics, interferometry, for optical and radio telescopes and antennas and so on. The holographic methods may be helpful in technology of manufacturing the above elements.
