The previous chapters have considered system resolution and, in particular, the size of object detail resolvable in the image. The basic approach has been based on system optical transfer function (OTF), or its modulation transfer function (MTF) approximation. A real system includes hardware, particularly the imager or camera and accompanying display, environmental effects such as motion and vibration, and channel effects such as atmospheric turbulence and particulate light scattering and absorption. Each phenomenon can be characterized by an MTF, which can be incorporated into the resolution models of the previous chapters.
This chapter is concerned with imagers or cameras, particularly charge-coupled devices (CCDs). The following two parts are devoted to environmental and channel MTF phenomena, respectively.
