TY - JOUR AB - Suitable measures are obtained for the uncertainty, corresponding to a fixed error of phase, in the object-image relation of a symmetrical optical instrument. For a thin lens with its aperture stop in contact with the lens the uncertainty is proportional to the distance between the object and the image. The formulae are utilized to determine the most accurate values of the coefficients in the object-image relation from observations including many pairs of co-ordinates.The results given by the phase criterion, unlike those derived by a purely geometrical treatment, are unaltered if the object and image spaces are interchanged.
