1.   Introduction

Using classical optical components such as filters, prisms, and gratings to separate the desired wavelengths before they reach the detectors results in complex optical systems composed of heavy components. A simpler approach might rely on a single optical system and a detector that responds separately to each wavelength band. Therefore, the development and fabrication of reliable detector arrays that respond to multiple wavelength regions has been a continuous endeavor. In this chapter, we will review the state-of-the-art single and multicolor detector technologies over a wide spectral range, for use in space-based and airborne remote sensing applications. Our discussion will be focused on current and most recently developed focal plane arrays (FPAs), in addition to emphasizing future development in UV-to-far infrared (IR) multicolor FPA detectors for next generation space-based instruments to measure water vapor and greenhouse gases.

Multi-band detector technology is progressing towards a number of exciting applications, such as remote sensing ...
