Abstract
A method and a device for time synchronisation of the optical transmission of data in free space from a transmitter to at least one receiver are discussed. In the method and the device, the time synchronisation between the image reproduction of a transmitter and the image recording of a camera is to be improved for the optical free space transmission between transmitter and camera. This is achieved in that a method and a device for time synchronisation of the optical transmission of data in free space from a transmitter to at least one receiver is provided, wherein an arbitrary time recording phase for an image recording by the camera is allowed, wherein an arbitrary recording start time for the image recording by the camera is allowed, an arbitrary implementation of an updating of the image content, typically line by line with a time offset, is performed for the imaging device, an arbitrary implementation of a readout timing and thus coherent shutter timings of the receiving camera is allowed, and a synchronisation is performed subsequently, on the basis of the image recordings not recorded in synchronised fashion.
