The method involves producing a series of light impulse by an impulse light source (3) in dependence of a detection of a reflector light impulse (11). The impulse light source is oscillated with a frequency, where the frequency is measured directly or indirectly. The length (X) of an optical path through a measuring point to a light sensor (4) is derived from the measured value of the frequency and the specific light speed on the basis of the impulse light source. An independent claim is also included for a device for determining a distance of a measuring point from a tissue surface of an eye. |
