The word "pixel" is often used to describe such an element, but this is technically incorrect because pixel refers to a single element of a spatially discrete light-producing device (such as a liquid crystal display). Whereas a sensel refers to an element of a discrete light-sensing device.

For example, the individual elements of a charge-couple device (CCD) image sensor, as used in many digital cameras, are sensels.
