Method for operating a medical optical tracking system, and medical optical tracking system

A method optical tracking system, comprising:

• a sensor or a camera, wherein the sensor or the camera are used for optical tracking,
• a light source configured to provide light signals for the optical tracking, and a control device,
• wherein the control device is configured to perform synchronization with at least one other medical optical tracking system and, to this end, to obtain sensor data acquired by way of the sensor or camera images acquired by way of the camera, which comprise detected extraneous light signals of the at least one other optical tracking system, to determine temporal properties of the detected extraneous light signals based on the obtained sensor data or the obtained camera images, and to define temporal properties of the light signals generated by way of the light source and/or a measuring window of the sensor or the camera, on the basis of the determined temporal properties of the extraneous light signals, such that the light signals from the light source and/or the measuring window lie in light signal pauses of the at least one other optical tracking system.
