Covert optically-scanning enhanced zoom pinhole lens technology

Abstract

Lens technology has been developed that enables a scene to be scanned optically whilst the lens remains stationary. The covert optically-scanning enhanced (COSE) pinhole lens technology also has the option of incorporating a zoom capability. This allows any target in the scene to be isolated and zoomed onto for further scrutiny. The COSE lens has an external stationary entrance pupil. The operation of the lens may be visualized as optically pivoting about this pupil plane whilst scanning the scene but physically remaining stationary. A technology demonstrator has been built and its performance is discussed. Further developments of the COSE technology are also discussed.
