Abstract
An optical method for the precise measurement of the angular errors of a table moving along a slideway is described. The system is arranged so that angular errors of the table give rise to sideways shifts of a random wavefront generated by a ground glass screen. The shifted wavefront is made to interfere with a reconstruction of the original unshifted wavefront produced by a hologram, and the angular errors determined from the interference fringes which appear. This technique has several advantages over usual autocollimator methods.
