A measuring device includes a movable probe head and an optical position sensing device for determining the spatial position and orientation of the probe head relative to a reference point. The position sensing device includes at least three position determination modules, arranged as a transmission unit or as a receiving unit, at least one position determination module being situated on the probe head, and at least one position determination module being situated at the reference point. A transmission unit has transmission unit marking element(s). A receiving unit includes optoelectronic detector(s) and receiving unit marking element(s), positioned in a defined spatial relationship relative to the optoelectronic detector. Visual contacts exist between at least some of the position determination modules. The position determination module on the probe head and the position determination module at the reference point are connected by at least one uninterrupted chain of visual contacts.
