<p>In a method for positioning the end (63) of a probe (60) on a target surface inside an open cavity in a test object, preferably on the nasal mucous membrane of a human being, the test object is fixed in a given position, whereupon an optical instrument (1) is so adjusted that the target surface is located essentially on its optical axis (I) and the position of the target surface in the longitudinal direction of the optical axis is defined. Then, the probe is attached on a holder (2), which is so operated that the end of the probe is placed essentially on the optical axis and is moved along this axis to the target-surface position defined with the aid of the optical instrument. A device and a system for implementing this method are also disclosed.</p> |
