Low-SWaP SWIR ALPD product development at SUI

As customer demand for infrared laser sensors increases, so too does the need for low cost, readily manufacturable SWIR imaging systems capable of asynchronous laser pulse detection (ALPD). Sensors Unlimited, Inc., an RTX company, presents recent advancements in its SWIR APLD products tailored toward high volume production and broad deployment. Detectors based on SUI's multi-mode tracking (MMT) readout integrated circuit (ROIC) have been adapted for uncooled operation over a wide temperature range, enabling the elimination of costly thermoelectric cooling. A chip-on-board device configuration has also been implemented, obviating the need for a windowed package. Automation of fabrication processes further reduces unit cost and provides improved device uniformity. Results of SUI's latest system performance assessments are also discussed.
