METHOD OF MANUFACTURING METROLOGICAL PHASE SCALE WITHOUT SUBSTANTIAL REMOVAL OF MATERIAL |
| 摘要 |
<p>A method of making metrological scale for scale reading apparatus includes directing a laser beam onto a scale substrate (12). The laser parameters are such that the local area of the scale substrate (12) on which the laser beam is incident is caused to be displaced, thus creating scale markings (16, 20, 22).</p> |
