Next-generation multi-mode tracking (MMT) technology developed by Sensors Unlimited Inc. (SUI), a Collins Aerospace Company, is presented. The technology provides focal plane arays (FPAs) with pulse detection capability in addition to traditional passive imaging, enabling more compact electro-optical (EO) systems with significantly lower power consumption. SUI’s latest MMT device is a short wave infrared (SWIR) FPA that features low-noise imaging, asynchronous laser pulse detection (ALPD), and time-of-arrival (TOA) capability in every pixel in the 12 μm pitch, 1280 x 1024 array. Simulated and measured results from the new FPA’s readout integrated circuit (ROIC), the 1280MMT, are given along with a comparison to SUI’s first multi-mode tracking ROIC, the 640MMT.
