Paper Abstract

Moller-Wedel has developed a very high accuracy angle measuring instrument. The angular resolution of the instrument exceeds 0.005 arcsec (-25 nano-radians). The repeatibility and absolute accuracy are in the 50 nano-radian range. The measuring range is at least 300 arcsec (-1.5 millirad). The instrument utilizes a linear CCD array with patented processessing techniques to determine the position of the return collimator image. The image is produced by an optimized optical system which projects a slit illuminated by light emitting diodes. High accuracy and stability also require thermal compensation in the opto-mechanic design of the instrument.
