Abstract:
1. A method of automatically producing digital linear images of a moving object, containing pixels having a substantially square aspect-ratio, independent of the range and/or velocity of the moving object, said method comprising the steps of: a) determining the range of an object moving relative to a planar light illumination and imaging (PLIIM) based linear imaging system; b) determining the velocity of said object moving relative to said PLIIM based linear imaging system having c) using the range and velocity parameters determined in steps (a) and (b) respectively, to determine a photo-integration time period parameter for the linear image detection array which ensures that said PLIIM based linear imaging system produces digital linear images of said moving object, containing pixels having a substantially square (i.e. 1:1) aspect-ratio, independent of the measured object range and/or velocity; and d) using said photo-integration time period determined in step (c) to control the photo-integration time period of the linear image detection array of said PLIIM based linear imaging system;
