Method for measuring three orientational degrees of freedom of a cube-corner retroreflector |
摘要 |
A method for determining three orientational degrees of freedom of a cube-corner retroreflector by obtaining with a photosensitive array an image of a three straight marks on the retroreflector and, with a programmable control device, taking a two-dimensional transform of the image and determining the three orientational degrees of freedom. |

1. A method for determining three orientational degrees of freedom of a retroreflector comprising:
obtaining on a two-dimensional photosensitive array an image of a first straight mark, a second straight mark, and a third straight mark on the retroreflector that has three mutually perpendicular reflecting surfaces; receiving by a programmable control device a two-dimensional digital array representation of the image; performing with the programmable control device a two-dimensional transform of the two-dimensional digital array to obtain coefficients of sinusoidal basis functions as a first transformed array; determining by the programmable control device the three orientational degrees of freedom based at least in part on the first transformed array; and storing the determined three orientational degrees of freedom. |
