Notes:
An autocollimator based optical system has been developed which allows the relative angular positions of separate reflecting targets to be measured with high accuracy over a relatively large area. Misalignments suffered by the autocollimator head during translation between different measuring points are accounted for by utilizing a large plane reference mirror. Accuracies better than ±2 arcsec have been obtained over a 0.5 m diameter circular exploring area.
