| Description | Focal Plane Assembly The AIRS IR Focal Plane Assembly (FPA) represents a major advance in infrared technology, incorporating a number of state of the art features in a space qualified, high reliability configuration. Key to its operation is an advanced hybrid PV/PC HgCdTe focal plane consisting of 10 PV modules and 2 PC modules each individually optimized for a particular grating order/wavelength range (see diagram). The PV modules consist of 1, 2 or 4 bi-linear arrays of back-side-illuminated HgCdTe detectors, each bump mounted to a low power, 1.2 m CMOS read-out integrated circuit (ROIC) that provides the first stage of signal integration and multiplexing. The 10 PV modules contain a total of 4208... |
