Optical readout device |
摘要 |
An optical readout device for reading out data from an electroluminescent data storage medium, comprising: a driving circuit (4) for driving the radiation-emitting material with a time-varying applied signal; a radiation detector array (6) for detecting radiation emitted from the data storage medium and for generating radiation detection signals; and a processing part (8) arranged to process the detection signals to distinguish a detection signal resulting from reading different types of marks in the data storage medium in dependence on a timing reference signal.
