Abstract :
A simple slot and bar type scanning device has been developed to measure the speed of optical images and the angular velocity of moving targets possessing intensity (or color) contrast. If the distance to the target is known, it can be used to measure target velocity. The instrument is sensitive only to the component of image velocity in the direction of scanner motion and is able to distinguish image speed of either sense.
