A complete optical probe scanning near field optical microscope is disclosed, comprising laser lighting system, monitoring system, sample support, light fiber probe scanning mechanism, three-dimensional rack and pinion adjustment, feedback control and data collecting system. Its basic idea that light fiber probe is fixed on tuning fork, through three -dimensional scanner, light fiber probe is made to scan on the surface of sample nearby, when light fiber probe is approaching the surface of sample, it will be influenced by effect of atom shearing force which will change concussion of tuning fork so that the information of distance between light fiber probe and sample can be obtained. The information is feedback to Z direction control system to make light fiber probe keep a distance to a constant value with surface of sample, whose appearance will be reflected by the information feedback, and light intensity collected by light fiber probe provides permeability of sample. The invention has the advantages of large scanning range, no limitation of sample, high modularization, convenient combination and change.
