Abstract
PURPOSE: To measure swells, undulations, etc. irrespective of the inclination of the subject surface by making the non-linear outputs for the coordinates of a photo detector by the reflected light from the subject surface linear with respect to the photo detectin position by a non-linear output for the coordinates of a photo detector by the reflected light from the subject surface linear with respect to the photo detecting position by a non-linear output amplifier.
