The Altair 13A-E, powered by SCD’s Cardinal sensor platform, is a low noise camera with extended spectral range from 0.6μm to 1.7μm. The camera uses SCD’s latest 1280 x 1024 format InGaAs detector with 10μm pixel pitch. The advanced digital ROIC provides advanced programmable on-chip features and very low noise performance.
The camera features Automatic Gain and Exposure Control to optimize image quality over a wide range of imaging conditions. A proprietary non-uniformity correction NUC provides nonuniformity correction over the -40°C to +70°C operating range with full performance from -30°C to +55°C. The camera has a TEC to cool the focal plane for low light-level imaging. On-board Correlated Double Sampling (CDS) delivers dynamic range of up to 70dB and low read noise <50 rms electrons for low-light operation.
A key feature of the FPA is on-chip digital Asynchronous Laser Pulse Detection (ALPD) that is enabled by proprietary circuitry on the FPA. ALPD provides a full-frame two-dimensional capture and X-Y position of short duration laser pulses in both daytime and nighttime. Multiple asynchronous spots can be tracked in the same FOV. This capability is completely independent of imaging, assuring optimal imaging capability with laser pulse detection.
