Abstract

Active-lighting sensors project light onto target objects or the scenes to obtain photometric measurements of the reflected light, including travel time and return angle. Therefore, understanding these sensor principles requires knowledge of the photometric characteristics of light and the mechanisms of light reflection. This chapter prepares the reader for detailed principle descriptions in later chapters by explaining various photometric characteristics of light and the definitions of brightness. Furthermore, a method for determining the relationship between the original brightness of light and the measured brightness is described.
