B6.2 - High Precision Multi Dimensional Displacement Sensors for Segmented Mirror Telescopes

R. Hoenicka & M. Wasmeier
New optical-infrared telescopes like the E-ELT (European Extremely Large Telescope) require the application of displacement sensors with enhanced specifications. The main mirrors of such big telescopes are designed from more hexagonal mirror segments. To adjust the whole mirror, all adjanced segments have to be adjusted multi dimensional. Therefore, on every edge on the back of the segments, so called edge sensors are mounted. With the experience from LAMOST (Large Sky Area Multi-Object Fiber Spectroscopic Telescope),...
