ABSTRACT:
A multiple degree of freedom displacement transducer and body thereof is used to measure linear displacements along and/or rotational or pivotal displacements about up to three orthogonal axes. In one embodiment, a displacement transducer body includes a first pivoting assembly and a second pivoting assembly. Each pivoting assembly has a support member pivotable relative to another portion about two orthogonal axes. A structure joins said another portion of each pivoting assembly together. In another embodiment, a displacement transducer includes a first support member, a second support member, and a cross flexure assembly joining the first support member to the second support member. The cross flexure assembly is arranged to allow the first support member to pivot relative to the second support member about two intersecting orthogonal axes. An angular sensing device is arranged to provide an output signal related to angular movement of the first support member relative to the second support member about at least one of the orthogonal axes.
