POSITION MEASUREMENT APPARATUS ABSTRACT OF THE DISCLOSURE Position measurement apparatus which utilizes a digital code to accurately determine the position of a movable body along a travel path. The digital code is selected to provide, for any N consecutive bits of the code, a bit pattern which is unique. Indicia defining the code, and a reader, are arranged for relative motion in syn- chronism with movement of the movable body. Translating apparatus converts each combination of N consecutive bits read by the reader into an address defining the location of the movable body relative to the travel path. In a preferred embodiment, the digital code is a maximum length digital code, which is conveniently generated by a polynomial generator. The bit length of the code, which is equal to 2N -1, is selected according to the length of the travel path and the desired resolution.
