Optic correlator for object co-ordinate acquisition in real-time display processing systems

摘要

The optic correlator comprises a lens (L') for shooting the image of a display (S') to be processed, a splitter assembly (D) for splitting the short image and a pair of split image supporting elements (V₁, V₂), each to receive a respective split image thereon, behind each image supporting element there being arranged a respective image processing assembly including a respective transparency (T₁₂, T₂₂), lens and sensor, (L", L", S₁, S₂), the output of the latter being supplied to electronic combinatory circuitry to be differentiated therein.
