摘要
An optical data recovery system including an optical receiver configured to receive light reflected from an optical medium and produce modulated data, a processing unit configured to transform the modulated data into a series of transform coefficients respectively identifying frequencies of the modulated data at respective times, and the processing unit is configured to identify from the series of transform coefficients defect coefficients associated with positions in the modulated data where the modulated data is corrupted.
