An investigation on methods to capture dual waveband image with CCD camera has been conducted. A split image concept has been identified after reviewing different possible configurations. A prototype development has been presented and the experimental image captured by the prototype has proven the proposed split image design concept. This concept can also be applied to middle or long wave infrared waveband. It has potential applications in surveillance, target classification or identification.
