EXACTD-332 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 3‑bit Gray code design of the EXACTD allows encoding of incident AoA with an angular resolution of ±6.0°, 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
- 3-bit design for precise ±6.0˚ 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
- Two reference channels are provided in each photodiode array for baseline signal level determination
