Abstract: An image fiber which includes a number of cores arranged at random and covered with an integrated clad. A method of fabricating an image fiber base material collected with a number of optical fiber strands in longitudinally drawn and aligned state comprising the steps of assembling the optical fiber strands of more than two different diameters from each other. In this manner, this method can eliminate the drawbacks of the conventional image fiber by arranging cores at random and can reduce a moire produced in case of connecting to a TV camera, and does not produce disioca- tions or pinholes of core arrangement in the section of the image fiber since a number of cores of the image fiber are arranged at random and are covered with integrated clad.

Abstract: Es wird ein faseroptischer Sensor mit einer von der Meßgröße beeinflußten Meßfaser und mit einer von der Meßgröße unbeeinflußten Referenzfaser beschrieben, bei dem die Meßfaser und die Referenzfaser aus einem einzigen Glasfaser-Lichtwellenleiter besteht, die einen lichtführenden Querschnitt (1) und einen dazu konzenrischen weiteren lichtführenden Querschnitt (3) aufweist. Der äußere lichtfüh rende Querschnitt (3) entspricht der Meßfaser, während der innere lichtführende Querschnitt (1) der Referenzfaser entspricht.

Abstract: A light source for a high resolution projection lithography system comprises a laser 10 and transforming optical apparatus which transforms the laser source into an optically equivalent self-luminous curved line source. The transforming optical apparatus comprises a two- dimensional array 20 of fly's eye lenses positioned to intercept a collimated parallel beam of light from the laser source and to produce a series of point or small area sources having a selected numerical aperture. An optical fibre array 22 is positioned so that the input end of each fibre receives the light output from one of the lenses in the array. The position of the input end of each fibre is chosen so that light from the illuminating lens underfills the fibre end to preserve the numerical aperture. The output ends of the fibres are arranged in position to produce a curved line source of a desired shape, e.g. a quarter of an annulus. Alternate embodiments are described in which different lens arrays can be selectively positioned to change the numerical aperture of the transforming optical apparatus.
