Image reversing array utilizing gradient refractive index elements |
摘要 |
An array of optical elements having imaging properties in one meridian and light-containment properties in another meridian for imaging a slit aperture in such a way that inversion of the image occurs across the width of the slit but not along the length of the slit. This one-way image reversal may be used to improve efficiency in photocopying.
