Influence of Gridboard Line Width and Spacing on Windscreen Distortion Measurements

Abstract

Optical distortions of aircraft windscreens are commonly measured on photographs taken through the windscreens of a large flat Cartesian grid called a grid board. Presently there are no accepted standards for the width of the lines or the size of the squares on grid boards. This study measured the effects of these variables upon measurements of vertical and horizontal magnifications to aid in establishing standards.
