Today s IR and visible sensors are used in two general configurations. One configuration - focal plane arrays, or FPAs - includes thousands or millions of elements, accessed through a readout- integrated circuit (ROIC). They, as well as the electronics for them, are discussed in Chapters 7 and 8. 

With only a few detectors, we can access each detector directly, so multiplexing is not required. The electronics can be built from discrete components - we do not require an integrated circuit.

The largest change in this edition is the addition of three chapters describing modem detector assemblies and their operation in some detail. Chapter 6 deals with single detector assemblies and small arrays - used, for example, in motion detectors, intm-sion alarms, and fire sensors. Chapter 7 describes ROICs and focal plane assemblies (FPAs) - the core of modern imaging systems. Chapter 8 describes the electronics needed to operate and test ROICs and FPAs.
