Light and Optical Imaging Systems
In this chapter, we shall discuss some elementary concepts in optics that are necessary to deal with the most common optical portions of imaging systems. Significant limitations are placed on the performance of such systems due to the amount of light from the object collected in the image, and the quantum and wave natures of electromagnetic energy. Practical electronic and optical phenomena that produce additional limitations are also introduced. The Fourier treatment of optical images and systems, which has proven so useful in both analysis and design, is also developed. The introduction of the scanning principle permits the calculation of the spectrum of video signals, whose shape is shown to be limited by the size of the objects depicted.
