EXACTD-362 Angle-of-Arrival Photodiode Module

The Excelitas EXACTD® platform is designed for use in Laser Warning Receiver Systems to detect and provide precise angle-of-arrival (AoA) information from direct and indirect scattered light from laser range finders, target designators, and active laser Electro-Optic (E.O.) systems.

The 6‑bit Gray code design of the EXACTD allows encoding of incident AoA with an angular resolution of ±0.8°, in either azimuth or elevation depending on the module’s orientation, over the ±45° field-of-view (FoC).

The Si and InGaAs detector arrays have a combined spectral sensitivity range of 500 – 1650 nm in a small compact TO-8 can.

Features & Benefits:

  • Spectral sensitivity range of 500 – 1650 nm
  • 6-bit design for precise ±0.8˚ AoA accuracy, in either azimuth or elevation
  • FOV is ±45˚ for both azimuth and elevation angles
  • Low- and high-sensitivity channels for wide dynamic range
  • Three reference channels are provided in each photodiode array for baseline signal level determination
