A two-element gradient-index photographic objective was designed. It operates at f/2 and has a focal length of 50 mm. The half-field of view is 21.8 degrees . The design is compared to the six-element new double Gauss photographic objective and performs well in comparison.
The possibilities of transmitting spatial information through a long gradient-index rod are presented. Spatial resolution vs rod diameter are optimized for both visible and IR transmitting systems.
The TPF dump analyzer (TDA) was conceived in an effort to create an intelligent programming assistant for the transaction-processing facility (TPF) programming environment where IBM System/370 assembly language is used. This particular program represents the first component of the system, which provides expert advice in the domain of solving run-time… (More)
