Electro Optical Testing Applications

Calibration of thermographic cameras requires the use of wide temperature range and the most accurate blackbodies.  Thanks to their radiometric calibration and their high uniformity, these blackbodies ensure a complete traceability of the thermographic data.

In order to meet the calibration requirements of sensors and instruments embedded in satellite missions, space grade sensor manufacturers need vacuum compatible blackbodies to accurately calibrate and carefully qualify the instruments including thermal imagers and other infrared sensors such as radiometers or spectrometers

Operating 24/7 blackbodies used to test detectors and core on production line must be reliable, traceable and accurate. Their structure allows them to be operated into narrow spaces, random orientation and possibly into climatic chambers. They can be easily remotely driven from the line management software.

The measurement of the optical performances of detectors requires extremely low noise driving electronics and acquisition module. During development phase, the FPA testing must also be compatible with any CMOS type detector.

Multi-axes systems are found on gimbals, drones and helicopters among others and include visible and low light cameras, thermal imager and laser rangefinder. Each individual axe of equipment has to be tested in addition to the alignment test between axes using large aperture collimators and multiple accessories.

Night Vision Devices (NVD), are mandatory and need to perform any times on the battlefield. Accurate testing of equipment strictly stick to the primary military standards. Spatial resolution, spot defect, gain, and distortion are tests performed with single low light Integrating Sphere or a complete collimator.
