| Abstract: | This paper describes a rotational stand,which can drive a helmet viewing window rotating to appointed any place for measuring several optical parameters,and let a fixed measuring beam pases through both of focuses when it passes though anywhere on camber.Thus is performs a correct measurement.What counts is the geometric character of the camber and unique design of the rotational stand. |
