Information is encoded in two broad ways: as electrical information and as information in other, non-electrical forms. In this section we will consider how we can measure electrical signals.

The retina in your eye, for example, is a transducer that converts photons into an electrical nerve impulse; your eardrum is a transducer that converts sound waves into a different electrical nerve impulse. A photon transducer takes a photon and converts it into an electrical signal, such as a current, a change in resistance, or a voltage.

Because these techniques use optical materials to disperse and focus the radiation, they often are identified as optical spectroscopies. For convenience we will use the simpler term spectroscopy in place of optical spectroscopy; however, you should understand that we are considering only a limited part of a much broader area of analytical techniques.

In this section we develop a common vocabulary that we can use in later chapters.
