DUAL SCAN OPTICAL PATTERN TRACER |
| 摘要 |
<p>9 C.W. 1089 The present invention applies to a circular scanning optical pattern tracer of the non-steering type. The scanner includes the normal circular scanning mirror and sensor and in addition a further circular scanning mirror and sensor to produce a scan of greater diameter than the normal scan. The signal from the second scan is used to indicate rapid changes of direction of the pattern by gating the produced signal through a gate produced from the normal scan.</p> |
