ABSTRACT:
Optical apparatus for measuring angles to a precision approaching the theoretical optical limit for a fixed aperture. Calculations and measurement of the angle are made on the basis of the displacement of a very detailed waveform on a multi-pixel detector from a known point on the detector. The angle this displacement represents is created by the angular displacement of a dispersive element attached to the object of interest. The beamline comprises an optical source, the dispersive element on the object, and a spectrometer which contains an echelle and the detector. The known point on the detector is established by aligning the beamline to a fiducial angle.
