Abstract
Imaging devices are very attractive as sensors on modern airborne platforms and there is a continuing trend toward widespread employment of imaging either alone or in combination with complementary technologies. In the civil domain, modern silicon CCD and CMOS image sensors are becoming extremely small, so that the package size of commercial miniature cameras is becoming dominated by the image forming optics, even if the latter is only a structure supporting a pinhole. We have previously reported a biologically inspired, near IR, imaging system that offers a wide field-of-view, thanks to the use of a multi-aperture sensor based on micro-optics which can be used to observe simultaneously in different directions. In this paper we describe our recent work on the design, assembly and test of a novel, all solid state camera that exploits spherical lens technology to provide a robust, wide field-of-view camera. We have also considered active fluidic lenses that can operate in the mid infra-red in order to provide additional functionality.
