Abstract: A method is given for finding a reference correction value of an index mark of an angular encoder. The angular encoder includes a first read head, a second read head, and a patterned element having incremental marks and an index mark. In a first instance and in a second instance, the patterned element is rotated relative to the read heads to obtain incremental readings from the first read head and the second read head and an index mark from the first read head. Based on these readings, a processor determines, in the first instance, a first reference position and, in the second instance, a second reference position. The processor determines the reference correction value based at least in part on the first reference position and the second reference position.

Abstract: A method for finding a reference correction value of an angular encoder index mark is given. The angular encoder has a first read head, a second read head, and a patterned element that includes incremental marks and an index mark. In a first instance, the first read head detects the presence of the index mark and, in response, the second read head generates a first analog signal. In a second instance, the first read head detects the presence of the index mark and, in response, the second read head generates a second analog signal. A processor determines the reference correction value based at least in part on the first analog signal and the second analog signal.

Abstract: A 3D measurement device sends a beam of light to a point on an object, receives the reflected light, and determines a distance and two angles to the point, one of the angles measured by an angular encoder, which includes a disk having incremental marks and an index mark. Light from the 3D device is rotated to reflect light from a reference reflector to produce a first synchronization signal. A first difference angle is determined based on counts of the incremental marks and on the first synchronization signal. Light from the 3D device is rotated to reflect light from the reference reflector to produce a second synchronization signal. A second difference angle is determined based on counts of the incremental marks and on the second synchronization signal. The reference correction value of the index mark is determined based on the first and second difference angles.
