In recent years scientific focal plane arrays (FPAs) have progressed to large multiplexed 2‐dimensional detector arrays of millions of pixels. The advantages of large‐format focal plane arrays (FPAs) for space science applications include greatly increased efficiency, sensitivity, ability to accurately assess backgrounds, high precision photometry and high precision positional information. While astronomy has greatly benefited from advanced large area detector arrays offering orders of magnitude increases in the observational capability, the technology is rapidly advancing and the future sensors designs have yet to realize the full potential of increased array formats. Large‐format FPAs have been fabricated with a variety of detector materials such as Si PIN, HgCdTe, InGaAs, InSb and Si:As. This chapter reviews the performance of the state‐of‐the art FPAs with particular emphasis on the challenges associated with the development of scientific detectors for use in space instrumentation. Examples of FPAs used in scientific optical payloads for atmospheric science, Earth observation and space astronomy are discussed.
