Ability to detect, aim and track targets and to assess the battle filed situation in combat provides tactical advantages and can determine the outcome of the battle. Electro-Optical Equipments provide this critical function, which is directly related to the combat strength in the battle filed. The cameras based on visible light sensors, Image Intensifier Tube based devices, thermal cameras using infrared detecting sensors and LASER sensor based devices coupled with the optics systems technology, which can be tailored to the specific tactical requirements, are used in battle filed. Further, these devices have become not only passive detection devices, but also become active and multi-functional devices that are capable of Automatic Detection, Aiming and Tracking. We must apply the Spin-on & Spin-off of the Military Technology and the Commercial Technology, which is based on Dual Use Science and Technology Paradigm, to further speed up the development process of Electro-Optical Equipment technologies.
