Features


  • High-Speed Imaging: Features a high-speed half wave rotating retarder imaging polarimeter operating in the LWIR spectrum, capturing imagery at different polarization states sequentially at up to 120 frames per second.

  • Exceptional Sensitivity: Offers the highest sensitivity among all Polaris’ LWIR imaging polarimeter offerings.

  • Advanced Filter System: Equipped with a 6-position filter wheel that can be chilled to 77K using a LN2 pour fill Dewar.

  • Dual Focal Length Lens: Integrated lens with dual focal lengths of 45mm/135mm for both wide and narrow field of view (FOV) viewing.

  • Comprehensive Software Control: Controlled by Grave’, a mature and complete software package designed for imaging polarimeters, offering real-time processing of radiometric and polarimetric data products, region of interest statistics, and processing.

  • Easy Connectivity: Operates with a laptop computer using a single connection GigE cable.

  • Data Fusion: Polarimetric information is fused with standard radiometric data for enhanced analysis.

Applications


  • Thermal Crossover Detection: Identifies man-made objects even when thermal contrast is low.

  • Cluttered Environment Detection: Distinguishes targets from natural background environments.

  • Facial Recognition: Enables enhanced biometric imaging in LWIR spectrum.

  • Environmental Monitoring: Detects oil on water and other surface contaminants.

  • Phenomenology Research: Supports studies of polarimetric signatures in real-world scenarios.
