Abstract
Representations are developed that characterize an article for identification by comparison with a reference standard as an escort memory. The representations are reduced to a binary tri-level code covering two extreme possibilities and an intermediate range for indecisive cases. Characteristics are sensed by light in one form by interferometer techniques.
