Optical dating measures the time that has elapsed since mineral grains were exposed to daylight. The technique is ideal for sediments in which all the grains were exposed to sufficient daylight at deposition to reset the optically stimulated luminescence (OSL) signal. However, in many environments the exposure of individual grains to daylight will be variable.
