摘要 |
In an arrangement for angular measurement using photoelectric means, in order to avoid instabilities in a required imaging system and to achieve a simple photoelectric evaluation the divided-circle lines (4, 9) and the measuring mark (11) are imaged via the same optical system and measured by means of a photoelectric micrometer (15). The measuring mark (11) is arranged at least in the vicinity of a divided-circle read-off point (9) and is illuminated together with the latter by a light source (1). <IMAGE>
