ABSTRACT:
An encoder interface for interfacing an encoder having a first part defining a first axis to a structure having a second part defining a second axis substantially parallel to the first axis includes a portion for translating the first part with respect to the second part in a direction transverse to the first axis and a portion for rigidly rotationally stabilizing the first part with respect to the second part against a rotation of the first part about the first axis induced by a translation of the first part with respect to the second part in the direction transverse to the first axis. A method for interfacing an encoder having a first part defining a first axis with a structure having a second part defining a second axis substantially parallel to the first axis includes the steps of translating the first part with respect to the second part in a direction transverse to the first axis and rigidly rotationally stabilizing the first part with respect to the second part against a rotation of the first part about the first axis induced by a translation of the first part with respect to the second part in the direction transverse to the first axis.
