InGaAs detectors and FPA’s for a large span of applications: design and material considerations

Performance benefits of charge-domain gain in active shortwave infrared targeting

“…3,4 SWIR capabilities have also reached technological maturity due to minimal losses in fiber-optic telecommunications and uncooled operation of indium gallium arsenide (InGaAs) detectors. 5,6 For all its benefits, however, passive SWIR imaging can suffer from low signal-to-noise ratios (SNRs) under reduced illumination conditions (e.g., at night). 7 Providing an active illumination source can remedy this problem in exchange for added size, weight, power, and cost (SWaP-C).…”
