- at least two DAS modules (2) which enable to obtain different angles of view by means of the various cameras it comprises,
- at least one DAS mounting plate (3) on which the DAS modules (2) are mounted,
at least one DAS vertical adjustment unit (4) which is connected to the DAS mounting plate (3) and which enables to change the angles of view of the cameras in the DAS modules (2) in vertical axis,
at least one DAS mast interface (5) which is connected to a mast that enables the DAS mounting plate (3), on which the DAS modules (2) are located, to be fixed to the floor,
at least one main body (6),
at least one infrared thermal camera (9) which detects the infrared radiation emitted by objects,
- at least one DTV camera (13) which provides day and night vision at all kinds of adverse conditions of the combat,

In a preferred embodiment of the distributed aperture sensor camera system (1) of the present invention, there are DAS modules (2) whose number can be increased as desired. Thanks to the fact that the DAS modules (2) are produced as a lightweight, small and ergonomic mechanical structure for expanding area of use thereof, users are also allowed to store spare devices. These DAS modules (2) are placed on the DAS mounting plate (3) preferably next to each other such that they will have different angles of view. The DAS mounting plate (3) is mounted to a mast, which is fixed to the floor and has a desired height, by means of a DAS vertical adjustment interface (4) provided on the DAS mast interface (5). While the DAS mast interface (5) is used for fixing the DAS mounting plate (3) to the floor, the DAS vertical adjustment interface (4) enables both mounting the DAS mounting plate (3) to the DAS mast interface (5) and moving the DAS mounting plate (3) in vertical axis. Thus, angles of view of the DAS modules (2) located on the DAS mounting plate (3) are also enabled to be changed upwards and downwards.
There is a main body (6) in the DAS modules (2), which are located on the DAS mounting plate (3), and whose number can be increased as desired. The openings located preferably at the top and side parts of the main body (6) are each covered by a top cover (7) and a side cover (8). By means of the openings provided on the top and side parts of the DAS module (2) and by removing the top cover (7) and side cover (8), the electronic and mechanical parts in the DAS module (2) are enabled to be easily replaced and maintained. By means of the infrared thermal camera (9), which is one of the cameras provided in the DAS module (2), and which preferably operates at the infrared band in the range of 8 to 12 μηι wavelength, the differences in the heat emitted by the objects in the field of view of the said infrared thermal camera (9) are detected and the said objects are located. The angle of view of the infrared thermal camera (9) can be changed upwards and downwards by means of a thermal camera vertical adjustment plate (12) that is connected to the main body (6) from the inside.
The infrared thermal camera (9) is connected to the software and hardware platform (17) via a thermal camera mounting plate (1 1), and comprises a fixed rear body (9.1), a waved washer SFGS wide lens (9.2), a moveable assembly (9.3), a fixing member (9.4), extension members (9.5) and a fixed front body (9.6). The radiation emitted by the objects in infrared band enters through a thermal window (10) provided at the front part of the infrared thermal camera (9), passes through the waved washer SFGS wide lens (9.2) located between the fixed rear body (9.1) and the moveable assembly (9.3), and reaches the moveable assembly (9.3). The waved washer SFGS wide lens (9.2) enables movement of the moveable assembly (9.3), which moves with temperature, back to its original position after the temperature decreases, and enables continuity of its movement as the temperature further decreases. There is one first inner body (9.3.1), one second inner body (9.3.2) and preferably three lenses (9.3.3) in the moveable assembly (9.3), and by means of these lenses (9.3.3), the said infrared radiation is projected on a sensor (not shown in the figures) which is preferably an FPA (focal plane array). After the analog data coming to the said sensor are detected, they are measured and converted to digital data and transmitted to the software and hardware platform (17).
In the preferred embodiment of the invention, the thermal sensor that is used employs an uncooled infrared detector. Since in uncooled modules, there is a static TEC (Thermo Electric Cooler) unit instead of the moveable cooler unit provided in cooled modules, there is no mechanical wearing that the moveable parts will be subjected to. Thanks to the uncooled infrared detector, power consumption of the device is reduced, MTBF (mean time between failures) value is increased and its cost is reduced.
By means of the athermalized infinity focused lens (9.3.3)having a fixed angle of view used in a preferred embodiment of the invention, the user does not have to change the optic adjustments (focus adjustments) of the infrared thermal camera (9) independent from the ambient temperature.
Thanks to the DTV (Daylight TV) camera (13) which is another one of the cameras provided in each DAS module; in addition to day vision, night vision is also enabled even if there is no light in the environment. Furthermore, the DTV camera (13) is not affected by glints and provides visibility to the user at adverse weather conditions such as dust, smoke, fog and haze. The DTV camera (13) is connected to a DTV camera mounting plate (15) located in the main body (6); and a DTV camera horizontal adjustment plate (16), which enables to change the angle of view of the DTV camera (13) to right and left in horizontal axis, is provided at the lower part of the said DTV camera mounting plate (15). The image coming to the DTV camera (13) enters through a DTV camera window (14) and is projected on a CCD sensor array (not shown in the figures) by means of an optic system provided in the DTV camera (13). The analog data projected on the said sensor is converted to digital data and the said data is transmitted to the software and hardware platform (17) by means of the wiring (K).
By means of a software in the software and hardware platform (17), a panoramic image, wherein desired number of angles of view are obtained, is generated by combining the video signals generated by a plurality of infrared thermal cameras (9) and DTV cameras (13) provided in each DAS module (2), and thus the entire area, which is intended to be protected, can be observed continuously via night and day cameras. The angle of view of the generated panoramic image can be increased up to 360 degrees depending on the number of DAS modules (2) and the angle of view of the cameras provided in each DAS module (2). Thanks to the fact that there is a minimum number of interface elements and a single connector output in the infrared thermal cameras (9) and DTV cameras (13) provided in the DAS modules (2) in the distributed aperture sensor camera system (1), the said DAS modules (2) can easily be replaced without causing a security weakness in case of a failure. Additionally, thanks to the day vision camera (DTV camera (13)), the infrared thermal camera (9) are turned off when not required and thereby service life of the device is increased. In one embodiment of the invention, there is a gimbal board (18) which is fixed to the DTV camera (13) by means of the gimbal board holder (19) located behind the DTV camera (13). The said gimbal board (18) is connected to the software and hardware platform (17) via the wiring (K). Thanks to the gimbal board (18), communication is converted from TTL (Transistor Transistor Logic) to RS232, DTV flex output is converted to wiring ( ), and DTV camera (13) input voltage is maintained at the DTV module lower value for DTV camera (13).
