Thermal sensor characterization

To test IR systems with the best reliability, Electro Optical Industries provides all the necessary equipment. 

Thermal sensor testing

From basic pyrometers to more advanced IR imaging systems, infrared sensors are electro-optical devices that convert the thermal radiation received into an electrical signal to give an accurate temperature reading. Whatever the device, they need to be reliably tested at several points through the manufacturing process: first during the development phase, then during the manufacturing and commissioning, and finally calibrated prior to delivery and frequently throughout being used in the field. From the civilian sector being used for industrial non-contact thermal monitoring to the security sector for surveillance purposes, these systems are used in a diverse number of settings. 

MRTD (Minimum Resolvable Thermal Difference), TOD (Triangle Orientation Discrimination), NETD (Noise Equivalent Temperature Difference), fixed pattern noise, MTF (Modulation Transfer Function), spatial resolution, FOV, distortion, optical axis alignment, dynamic range, saturation level, temperature stability, and uniformity, are just some of the large range of parameters that can be tested to evaluate the performance of a thermal sensor. 

Electro Optical Industries provides:

  • Several different off-axis collimators, to project the test image of a target in front of a blackbody,
  • a range of standard targets, with various patterns and sizes required to perform standard measurements, EOI can also supply any type of pattern to meet specific customer needs,
  • a wide range of infrared reference sources, with a highly stabilized temperature between  -173°c to +3000°c.
