Abstract

An irregular polygon scanner used in infrared systems has a number of plane mirror facets which are tilted at a variety of angles with respect to each other and also to the rotational axis. As the faces do not possess angular symmetry, it is difficult to manufacture irregular polygons in a block. Only methods available for mass production of such polygons are replication or single point diamond turning. Due to individual working of irregular polygon, the production cost also becomes very high.
