Abstract
A calibration device provides a lightweight rigid support for a long arm. The rigid support includes thin flat sheets separated by a light weight filler. The filler prevents wrinkling or rippling of the flat sheets. Three ball trihedral nest kinematic mounts may be attached to opposite ends of the long arm for precise mounting of retro-reflectors for optical calibration, or precision spheres may be attached to the opposite ends of the long tube to obtain a mechanical calibration standard.
Claims20
A calibration device, comprising:
- a long arm configured to support precisely spaced apart calibration artifacts;
- a header filled with a thermally stable filling surrounding the long arm;
- kinetic mounts attached to opposite ends of the arm;
- a support portion comprising:
- at least four flat sheets made from thin material attached to the header;
- and
- a filler holding the flat sheets to a fixed spacing.
