Abstract
An apparatus for measuring angles and/or distances includes a sensing head with sensors for determining absolute values and incremental values. The incremental values are provided between two successive absolute values. The apparatus further includes a scale embodiment, which is assigned to the sensing head, and a device for forming a total absolute value from an absolute value determined by a sensor and an incremental value determined by a sensor and for providing this total absolute value in binary/digital form over the entire operating range. The entire signal processing is therefore carried out in the sensing head, so that the complicated signal transmission can be simplified significantly, and complicated peripheral electronics can be dispensed with. A method of measuring angles and/or distances is also provided.
