Method for the optoelectronic scanning of a pattern reproduced on a surface, particularly in a tape measure |
摘要 |
This pattern modulates the light flux of a light source and forwards it to an optical sensor, the output of which is interrogated by a storage and evaluating device, the light source for generating the light flux being active within a scanning period which is selected to be as short as possible in comparison with the duration of the scanning period.
