Inferior mirages over sun-exposed roads often appear in isolated strips at their near sides and the reflected scenery exhibits multiple images. This effect is explained as due to slight undulations of the road's surface. At the same time, some of these images, although they are reflections, are not inverted. Photographic material illustrates this phenomenon and a ray tracing study is presented that confirms these conclusions.
在阳光照射的道路上出现的下蜃景通常在道路近端以孤立的条带形式出现,反射的景物呈现出多个影像。这种效应被解释为是由于路面的轻微起伏所致。同时,这些影像中的一些,尽管它们是反射影像,但并未颠倒。摄影资料说明了这一现象,并给出了一项光线追踪研究,证实了这些结论。
