ABSTRACT:
In an exemplary embodiment, an ultrasonic scanning apparatus has an articulated support for at least one scan head and angle indicators for determining point- and/or direction-coordinates of the scanning. An angle detection and processing is desired which is considerably simplified as compared with the state of the art but which is nevertheless highly precise, interference-insensitive and cost-economical. This is achieved by at least one synchro system for supplying a sine and/or cosine of the angular value of the rotational angles and including a purely electric cascade interconnection of individual synchros so as to form a synchro control transformer- or resolver-chain or a mixed chain consisting of synchro control transformer- or resolver-chain or a mixed chain consisting of synchro control transformers and resolvers for the purpose of conversion of sine- or cosine-values, respectively, of the rotational angles into sums and/or differences of individual angles and/or into sine- or cosine-functions, respectively, of such angular sums or angular differences.
