ABSTRACT:
An arrangement for determining the position of a surgical microscope uses signal transmitters and signal receivers. Light emitting diodes that emit coded light signals and light receptors for receiving the coded light signals are arranged in various locations in space. Reflectors having narrow-bond reflection characteristics are arranged on the microscope so that the light reflected can be identified.
