Abstract
Extracting data in pulsed light, the method includes receiving input light at an image intensifier tube. At a power supply coupled to the image intensifier tube, current to the image intensifier tube is varied to implement automatic brightness control of the intensifier tube based on intensity of the input light received at the image intensifier tube. At a signal processor coupled to the power supply, changes in voltage or current supplied by the power supply occurring as a result of changes in the intensity of the input light to the image intensifier tube are detected. Based on the changes in voltage or current supplied by the power supply, data embedded in the input light to the image intensifier tube is extracted.
