Abstract
A one-dimensional scanner system for two-dimensional image acquisition includes a flying spot scanner for scanning in a line at a first velocity in a first direction across an object which is moving at a second velocity in a second direction transverse to the first direction; the first and second velocities establish a first sample rate in the second direction for defining a pixel size in the second direction; a timing device for detecting the velocity of the object in the second direction and generating a sample rate in the first direction and a frame accumulator for reading and storing each line scanned, assembling a two-dimensional image of the object and reading out that image; the frame accumulator including a compensation device responsive to the second sample rate for normalizing the second sample rate with the first sample rate to eliminate distortions in the pixel size and two-dimensional image in the first direction.
