Multi-Sensor Systems
Multi- sensor surveillance systems represent a fast growing group of electro-optical systems of critical importance in both defense and civilian applications. At the same time they are the most expensive groups of electro-optical systems. Most advanced but rarely met multi-sensor surveillance systems are built from a long series of sensors like thermal imager (or two thermal imagers, color VIS camera, low light VIS-NIR camera, SWIR camera, laser range finder, laser designator, laser pointer, illuminator located on a stabilized platform and such systems. Simpler systems built from two-three sensors located on smaller stabilized or non-stabilized platforms are more common.

Boresight Systems
Boresight is a process to align optical axis of single system or a series of optical or electro-optical systems with a certain reference optical axis or mechanical axis. Proper boresight is particularly critical in case of multi-sensor electro-optical surveillance systems built from a series of systems like thermal imager, VIS/NIR camera, SWIR camera, laser range finder, laser pointer.

Thermal imagers
Thermal imagers sensitive in MWIR and LWIR spectral bands are one of crucial surveillance technologies for defense/security sector. These imagers have also found mass applications outside defense sector. Testing thermal imagers is needed for both manufacturers, maintenance workshops and final users for a set of different and important reasons. Hi-tech test equipment can help significantly in manufacturing, maintenance, training, purchase optimization, and optimal use of these expensive imagers.

VIS-SWIR FPA's
Imaging electronic sensors sensitive in visible, near infrared, short wavelength infrared spectral bands that generate two dimensional electronic images have found mass applications in industry, defense, security, science, environmental protection, medicine etc. Imaging sensors sensitive only in VIS/NIR range are almost exclusively silicon chips manufactured using a series of technologies: CCD, CMOS. ICCD, EMCCD, EBAPS, sCMOS in color or monochromatic versions. Color VIS/NIR sensors are sensitive to light only in visible range when monochromatic VIS/NIR sensors are sensitive up to about 1000nm.

Rotary wheels
Rotary wheels are one of basic blocks of systems for testing imaging EO systems. They are needed to enable motorized exchange of active target at collimator focal plane. There are usually 8 holes in the wheel for targets (other numbers are also possible). Wheels are covered with a black high emissivity coating (emissivity at least 0.97).

SWIR Imagers
SWIR imagers (short wavelength infrared) are an important group of surveillance electro-optical imagers due several reasons. First, advances in InGaAs technology enabled design of relatively low cost SWIR imagers. Second, InGaAs imagers are very sensitive and can generate images of observed scenery even at dark nights. Third, SWIR imagers are less vulnerable to bad atmospheric conditions than TV/LLLTV cameras working in visible/near infrared band. Fourth, SWIR imagers can generate hi-res images even if they are built using much smaller optics than used for design of thermal imagers.

Fused Imagers
Fused imagers (fusion multi-sensor imaging systems) offer increased surveillance capabilities due to fusion of classical thermal image with classical visible image. The fusion systems are typically built by combining optically images from thermal imager and classical night vision device, or by combining digitally images from thermal imager and digital night vision devices (or electronic VIS-NIR camera).

Collimators
Collimators are optical systems used to imitate standard targets placed in "optical infinity" (very long distance). The collimators are used for projection of image of reference targets into direction of tested imagers. According to type of optical elements used in design, collimators are divided into two groups: reflective collimators and refractive collimators. Reflective collimators due to their wide spectral range are almost exclusively used in systems for testing thermal imagers and are also preferable in systems testing TV cameras, SWIR imagers, laser systems or multi-sensor surveillance systems. Refractive collimators are mostly used in systems for testing night vision devices or TV cameras working in visible/near infrared range.

VIS-NIR Cameras
Surveillance cameras based on CCD/CMOS/ ICCD/ EMCCD/EBAPS imaging sensors sensitive in visible and near infrared range are widely used in many long range surveillance applications as independent imagers or as part of a bigger multi-sensor surveillance systems. Majority of VIS-NIR cameras are used for day level applications but an increasing number of these cameras is used to enable surveillance in both night and day conditions. In both cases it is important to verify performance of these cameras under varying illumination conditions from very dark nights to ultra bright days. Important missions can fail due to too low sensitivity of VIS-NIR cameras at night conditions (dark, noisy images) or due to too low dynamic at ultra bright day conditions (saturated, blurred images). Next, it is important to use VIS-NIR cameras that generate high quality images in order to achieve maximal effective surveillance ranges.

Target simulators
Simat simulator is an advanced hardware simulator capable to simulate in infrared range several targets on quasi uniform background. In detail Simat simulator is a modular image projector capable to simulate in infrared range variable intensity, variable angular size, variable spectrum, spatially and temporally dynamic airborne type targets on quasi uniform background. Basically the aim of Simat to enable simulation typical airborne targets like aircrafts or helicopters for infrared imaging sensors used for surveillance of these targets. Optionally Simat can be modernized to enable simulation in both IR and UV/visible ranges as the projectors are built using broadband reflective optical elements.

Laser systems (laser range finders, laser designators, laser receivers, laser trackers, laser pointers) are one of crucial technologies for defense/security sector. Laser systems have also found mass applications outside defense sector.

Optical tables
The primary goal of a well designed optical table is to eliminate relative motion between components of test system located on the surface of the optical table because such motion can generate measurement errors.

Image Intensifiers
Image intensifier tubes (IITs) are vacuum tubes that amplify a low light-level image to observable levels. Image intensifier tubes are the most important modules of night vision devices that play crucial role in defense/security/industrial applications.Technology of manufacturing of image intensifier tubes is very difficult and performance parameters of modern IITs varies even within the same technological process. Next, test report offered by manufacturers cannot be fully trusted because there are some differences in test methods used by different manufactures. Further on, there are literature sources presenting conflicting claims of different manufacturers. It is quite common to find on the world market two night vision devices (or two image intensifier tubes) of the same data sheet parameters but of totally different image quality. Inverse situation is possible, too. Due to reasons mentioned above testing image intensifier tubes is of critical importance for both their manufacturers, manufacturers of night vision devices (NVDs) and final users of NVDs.
