POLARIZATION BEARING DETECTION TYPE TWO-DIMENSIONAL LIGHT RECEPTION TIMING DETECTING DEVICE AND SURFACE SHAPE MEASURING DEVICE USING IT |
| 摘要 |
<p>The detection light of polarization bearing is synchronized with slit light scanning so as to two-dimensionally record the polarization bearing using a pair of analyzers (5,6) and storage type image detectors (7,8) that are in crossed Nicols arrangement. An independent claim is also included for surface shape measuring device.</p> |
