Abstract
Advances in infrared (IR) focal plane arrays (FPA) have steadily encroached upon the limits of technology. Larger formats, smaller detectors, and higher operability have improved performance. The next step is an FPA that accepts photons and converts them into a corresponding digital word. This advancement reduces susceptibility to electromagnetic interference (EMI) at the interface and minimizes the complexity of the downstream electronics. Attempts to integrate this function in an FPA involved technical difficulties such as increased power, low resolution, and non-linearity. Santa Barbara Focalplane has successfully developed a number of different types of digital FPAs with improved performance and lower power than equivalent analog FPAs. These FPAs have been integrated into closed-cycle dewar-cooler assemblies (IDCA) and are being shipped in production quantities.
