These techniques are based on two phenomena thermally stimulated luminescence and optically stimulated luminescence. Today, its methods are indispensable for research and development activities as well as for production technology. This is very different from calibration, where known quantities are measured by a new method and the result compared with the true value or with measurements.
Optical measurements techniques and applications oliver. A pulsing unit has been developed enabling the measurement of pulsed optically stimulated luminescence posl and together with a fast photon counter this allows detailed studies of luminescence phenomena during both the stimulation pulse and the delayed luminescence after the stimulation pulse. Laser measurement technology has evolved in the last years in a versatile and reflationary way. The tracer application of luminescence has key advantages including ease of measurement, relatively low cost, and applicability to geologically ubiquitous quartz and feldspar sand and silt. When luminescence occurs, the system loses energy and if the emission is to be. Other methods are needed to estimate uncertainties due to. All other forms of light emission are called luminescence.
