96. Developments and Applications of the Absolute Multiline Technology

Dr Heinrich Schwenke (Etalon AG)

14/06/2016, 09:00

The presentation will report recent developments and applications of the Absolute Multiline Technology. Examples are the deformation measurements of telescopes or the monitoring of large CMM. It will also introduce a company/institute wide installation to deliver the "absolute meter" to different applications.

73. Status of FSI network development for the PACMAN project

Mr Solomon William Kamugasa (CERN)

14/06/2016, 09:20

We present our strategy for fiducialising CLIC components within the final PACMAN alignment bench using Frequency Scanning Interferometry (FSI). We have developed a device to enable Absolute Multiline Technology perform absolute distance measurement to targets in different directions from the same point. This allows us to employ the multilateration technique to determine the coordinates of...

79. Recent developments in the field of frequency scanning interferometry

Dr Michael Campbell (NPL)

14/06/2016, 09:40

Two questions for which people ask for help from NPL are: ‘How good is my instrument?’ and ‘what are the uncertainties associated with my measurements?’ At NPL we felt an instrument was needed which would inherently answer these questions with every measurement. Therefore we have built a coordinate measurement system that is self-calibrating with compensation for systematic errors, calculates...

81. Results of the “Absolute Multiline” Measurements on the Very Large Telescope

Dr Samuel Lévêque (ESO)

14/06/2016, 10:00

The “Absolute Multiline” has recently been tested on the Very Large Telescope (VLT) to monitor the Rigid Body Motion between its primary and secondary mirrors by forming an optical hexapod. This test is part of a more general evaluation of the adequacy, performance and robustness of such a measuring technique for monitoring the inter-mirror position of the future European Extremely Large...
