IPC: G02B21/14
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain a compact scanning type optical microscope which has resolution exceeding a diffraction limit and is effective even when the intensity of returning light from an inspection sample is low. SOLUTION: Light from the inspection sample is made to finely scan at high speed by a light deflector 6 and bisected by a light splitter 7, so that the interfering light of the light passing through similar optical fibers 10 and 11 having an enlarging rate in inverse proportion to the refractive index of the optical fiber is obtained in respective optical paths. Therefore, the intensity of the light from one point in focus spot light on the surface of the inspection sample obtained by focusing irradiating light is made almost zero by interference. The intensity of the light emitted from a point getting away from the point becomes higher in the case of the interference. By scanning with the returning light beam from the inspection sample by the light deflector, the position of one point where the intensity of the light becomes almost zero is changed by the interference in the focus spot light on the inspection sample.
