Frenel Imaging

Frenel Imaging develops software and sensor configurations for polarimetric thermal imaging. Its TPiCORE image-processing framework works with micro-polarizer arrays to extract polarization information from emitted thermal radiation, producing additional contrast and classification features beyond conventional thermal intensity. The company combines image-signal processing with application development for defence, industrial and machine-vision customers.

In counter-uncrewed-aircraft systems, the technology provides passive day-and-night detection and classification using thermal and polarimetric signatures. That information can help distinguish small aircraft from birds or background clutter, maintain tracks near or below the skyline and feed a wider surveillance or response system. Frenel supplies the imaging and perception layer; radar, radio-frequency detection, platform control, command decisions and any physical countermeasure are separate elements supplied by the integrator and operator.
