ABSTRACT:
An array of photosensitive imaging sensors connected to a digital computer is utilized to measure selected dimensions of objects upon which the photosensitive array is focused. Two sets of information in the form of analog signals generated by the photosensitive array, both with and without an object in view, are converted to digital form and stored in a memory. The two sets of information contained in the memory are compared to thereby create digital signals indicative of the dimensions of the object. These digital signals are converted to dimensional form and displayed.
