<p>The device has a rotor with rotor blades (35) that is drivable in a controlled manner. The rotor rotates in front of an outlet window (8) and/or an inlet window (9), and is driven so that light beam and/or reflected beam is passed in a time coordinated manner exactly in an intermediary space between two sequential rotor blades of the rotor and a drive. The rotor is coupled with a control of an optical probe head (1). A rotor axis (34) is arranged between the inlet window and the outlet window of the probe head, and the rotor covers both windows. An independent claim is also included for a method for using a protective device.</p> |
