The night sight clip on module based on uncooled infrared detector technology was designed around an infrared camera
module. This camera module uses an uncooled 640 x 480 detector and has a highly integrated electronic.
The night sight clip on module has a magnification of exactly one and a precisely pre-aligned line of sight with respect
input to output. The module is designed to be used in front of a standard day sight telescopic aiming optic on an assault
rifle. The sophisticated optical design of the clip on module eliminates the need of a realignment of the day sight optic
when the module is placed in front of it. Also there is no need for a precise placement or angular alignment of the
module in front of the day sight aiming telescope.
The signal of the IR camera is displayed on a small monitor. This picture is then collimated to infinity and used as the
input for the daysight telescope. The rifleman sees in the eyepiece of his telescopic daysight an infrared image of the
scene. The magnification is done by the setting of his telescope. The aiming reticle is still the one from the day scope.
The optical design of the night sight clip on module and the electronic block diagram will be presented.
The Small Arms Video Sight is part of the optronical sights developed for the German IdZ-ES program (German Army
Soldier-of-the Future Program - Enhanced System) [1]. The aim of the development was to use this highly integrated
sight on three different rifles (G36 = the assault rifle of the German soldier optional with a 40mm underslung grenade
launcher, MG 4 = a light machine gun , PZF3 = a 60mm / 110mm bazooka). The Video Sight will be used for
observation, target detection, recognition and identification, direct and indirect aiming and shooting with ballistic
calculation and aiming mark correction, still and video picture capturing and wireless transmission, determination of a
located target position by distance and angle to the own position and so on. To perform all these tasks the Video Sight is
equipped with an uncooled IR and a CCD camera, a laser range finder, a digital compass, angle sensors, electronic
display, all this sensors highly integrated and controlled by an operating system.
