Abstract: Abstract The principles of operation of an instrument which can measure the wavefront aberrations, transverse-ray aberrations, and spot diagrams of an optical system are described. The instrument functions by scanning the pupil of the optical system with a ‘ray’ of light and measuring the coordinates of the point of intersection of the ray, with the image plane, using a position-sensitive detector. An image-dissector tube is used as the position-sensitive detector. The instrument also has a facility for generating a polynomial function which can be matched to the measured aberration curves in order to determine directly the aberration coefficients.
