An investigation for the development of an integrated optical data preprocessor
A 1978 NASA technical report by C. M. Verber, D. W. Vahey, R. P. Kenan and V. E. Wood on integrated optical data preprocessing, written for engineers working on thin-film optical computing devices. The pictures are plain line drawings: axis-labelled signal-versus-phase-voltage curves, one traced from an oscilloscope and one smooth, plus flat mask layouts of interleaved triangular electrodes with numbered contact tabs, useful as diagram stock, repeating geometric pattern, or technical page furniture.
