Rotating mirrors
First Claim
1. A rotary mirror comprising a rotary carrier having a plurality of mirror surfaces arranged around a periphery of said carrier, and the carrier having an average overall density except in selected regions whose density is different from the overall density and which selected regions are located and shaped to reduce spatial variation in any centrifugal distortion of the periphery of the carrier when the carrier is rotated wherein the different density regions are provided by the introduction of a material at selected regions within the carrier.

Abstract
Rotating mirrors and methods for producing rotating mirrors with reduced variation in centrifugal distortion are disclosed. Pins (52) having a density different from that of the remainder of the body (51) of a rotating mirror are provided and located to reduce variation in centrifugal distortion when the mirror is rotated at high speed.
