Abstract

This paper will present an ultra-light weight, 65 gram, dual-imaging infrared camera. The camera has been optimized for use in small micro-air vehicles, as well as other weight-sensitive applications. There are three key features of the system. First, it has no moving parts, as the calibration shutter has been removed. The technological hurdle of removing the shutter from conventional un-cooled VOx imagers was overcome by innovative software correction techniques. This shutter-less operation renders the camera significantly more rugged and allows its use in environments that were previously intolerant of such systems. Second, the assembly contains a one-piece rigid-flex board design. This adds significantly to ruggedness and assembly simplicity. Finally, the two lens/sensor assemblies incorporate sturdy, yet extremely light-weight housings. Prototype system thermal sensitivity measurements achieved less than 50 mK NETD with 10.5 mm efl/ f0.86 optics.
