| 21. | An essential component of a diffraction unit was a very accurate angle measuring device known as a goniometer.
|
| 22. | Once tuned, the operator rotated the antennas or goniometer looking for peaks or nulls in the signal.
|
| 23. | These goniometers do come in different forms that some would argue will actually increase the reliability of the tool.
|
| 24. | He invented the camera lucida ( 1807 ), the reflecting goniometer ( 1809 ), and the Wollaston prism.
|
| 25. | Goniometers are used to measure angles of fractures and other features in a core sample relative to its standard orientation.
|
| 26. | A mast above the cabin held a pair of antennas that were used with a goniometer for height-finding.
|
| 27. | In 1910, the Number 3 Dial Sight, a refined version with a telescope and compass, replaced the goniometer.
|
| 28. | Core drills are used frequently in Oriented Core Goniometer commonly used when logging core and analyzing contacts and other structural features.
|
| 29. | This approach avoids putting a large mechanical load on the diffractometer goniometer, making it easier to maintain fine angular resolution.
|
| 30. | An older type of goniometer is the four-circle goniometer, and its relatives such as the six-circle goniometer.
