Abstract
The evaluation of lens distortion by photographic and visual methods is discussed. Measurements made on a single lens using the two methods are reported. The precision of measurement of each method is determined which shows that the observed differences must be attributed to systematic error. Various sources of systematic error are considered. Uncompensated differential plate tipping is identified as the most probable cause of the observed differences. A method of correction is developed. It is concluded that when work is done with extreme care and with due account taken of various insidious sources of error, it is possible to achieved comparable results with either methods.This publication has 2 references indexed in Scilit:
