Abstract

Distortion is an issue that arises when designing Army Helicopter sensor packages. F-Theta versus F-Tan-Theta distortion is consistently one of the most important and least understood facets of the system. This is especially important when dealing with multiple sensors that have to use the same display. Arriving at the optimized optical solution can be a very involved and difficult design process. This paper explains what the problems are, the possible solutions, and the results of the design choices made along the way. It will elaborate on how each design choice affects image resolution, field of view (FOV), sensor fusion, and the apparent motion artifacts that are caused by mismatched distortions. The goal is to develop a better understanding of the problem, which will enable us to design the best possible optical system for the helicopter pilot.
