Abstract
An interchangeable chromatic range sensor (CRS) probe for a coordinate measuring machine (CMM). The CRS probe is capable of being automatically connected to a CMM under program control. In one embodiment, in order to make the CRS probe compatible with a standard CMM auto exchange joint, all CRS measurement light transmitting and receiving elements (e.g., the light source, wavelength detector, optical pen, etc.) are included in the CRS probe assembly. The CRS probe assembly also includes an auto exchange joint element that is attachable through a standard auto exchange joint connection to a CMM. In one embodiment, in order to provide the required signals through the limited number of connections of the standard CMM auto exchange joint (e.g., 13 pins), a low voltage differential signaling (LVDS) serializer may be utilized for providing additional control and data signals on two signal lines.
