The book has thus far addressed dynamic range issues, concepts, and solutions for 2D visible-light image sensors. Dynamic range is of course a more general concept that also applies to human vision, audio, amplifier design, and other fields of engineering. This chapter considers non-visible and 3D imaging devices; these technologies will not be covered in detail, but rather it will be shown that dynamic range, HDR, and XDR exist in imaging outside the scope of this book.
