Image degradations of an aerodynamically shaped optical window
Abstract
The inclined cylindrical window, an aerodynamically shaped window used in mounting sensors on the sides of vehicles, is considered with particular attention given to the effects of window optical distortion on imaging-system performance. Several cylindrical window designs are analyzed, and different approaches to optical correction of the window effects are discussed. It is concluded that the feasibility of an optical sensor/cylindrical window combination can be assessed only by considering the platform aerodynamic requirements, the projected stress and thermal environment, and the system detection requirements.
