METHOD OF SCALE MANUFACTURE WITH LASER AND SENSOR AND FEEDBACK MEANS FOR PRODUCING SCALE MARKING WITH DESIRED DEPTH |
摘要 |
<p>The present invention relates to an apparatus for the manufacture of a metrological scale comprises a scale substrate (18), at least one laser (20) for producing scale markings on the scale substrate (18), a sensor (30) to detect the depth of the scale markings produced on the scale substrate (18), and a feedback system which uses data from the sensor (30) to adjust parameters of the system to produce scale markings with the desired depth.</p> |
