A self-emitting optical probe having a built-in light-emitting function, wherein the light-emitting mechanism and the aperture portion of the optical probe are formed by depositing an electrically conductive thin film, an organic thin film, and a metallic film by means of sputtering and oblique vacuum evaporation while rotating the core. The self-emitting optical probe enables an inexpensive scanning near field optical microscope yet simplified in operation.

In a method for sharpening a probe, a probe preform having a longitudinal axis is at least partially immersed in a mixture containing at least an etch solution and a non-etch solution having a lower specific gravity than and which is not miscible with the etch solution. The probe preform is moved in the mixture along the longitudinal axis thereof during etching at a speed which does not exceed a taper length forming speed for a probe preform which is not moved in the etch solution during etching. An end of the probe preform is etched into a sharp tapered tip having a taper angle greater than that obtained for the probe preform which is not moved during etching.

A microscopic area scanning apparatus is provided with at least three hollow cylindrical piezoelectric elements each driven in three XYZ directions by one of divided electrodes. Three or more hollow cylindrical piezoelectric elements are arranged on a circumference of a common plane. Balls are each axially provided at a free end of the hollow cylindrical piezoelectric element. Ball retainers rotatably and slidably support a respective ball in contact therewith. A sample stage is fixed to the ball retainers. A table fixes the hollow cylindrical piezoelectric elements on the circumference of the common plane. Thus, the microscopic area scanning apparatus can realize both a wide X-Y scanning range and a high Z-direction resonant frequency without utilizing an elastic hinge.

A scanning near-field optic/atomic-force microscope comprises a holder for holding a sample immersed in a liquid, and a plate disposed over the holder for covering a surface of the liquid and for transmitting therethrough a laser light. A probe has an optical propagation body terminating in a distal end, and a light reflecting element disposed thereon, and the probe is immersed in the liquid. A light source emits a light which is introduced into the optical propagation body of the probe, which guides the light through the probe and out the distal end thereof to irradiate the sample. A detecting device detects information from the light irradiated on the sample and converts the information to an electric signal. A laser source irradiates the light reflecting element of the probe with a laser light for detecting a bending amount of the probe resulting from an interaction between the sample and the probe. An angle adjusting mechanism adjusts an optical axis of the laser light transmitted through the plate. A photoelectric conversion device receives the laser light reflected from the light reflecting element and converts the reflected light into an electric signal. A moving mechanism moves the sample relative to the probe, and a distance control device controls a distance between the surface of the sample and the distal end of the probe.

An easy to use scanning probe instrument such as a microscope or memory device is provided with a probe which does not require optical alignment. The scanning probe is a cantilever probe adapted to undergo relative movement with respect to an object such as a sample or a recording media. Optical interference and/or displacement of the cantilever probe caused by interaction with the object while the probe is being scanned across the object is measured to determine characteristics of the object. The cantilever probe has a base member, a cantilever formed in the base member, at least a portion of the cantilever being elastically deflectable to enable the cantilever to be displaced in a given direction. A waveguide extends through the base member and has one end surface disposed proximate the cantilever, the one end surface being positioned perpendicularly with respect to the given direction of displacement of the cantilever and being spaced from the cantilever by a distance sufficient to allow displacement of the cantilever by a desired amount in the given direction.

摘要:
A radiated light of a light source for optical characteristic measurement is amplitude modulated by an optical modulator and directed into a light-propagating probe. A phase and intermittent rate of the optical modulator are adjusted by a phase shifter. A sample characteristic measuring light is radiated onto the surface of the sample from the distal end of the probe. A light transmitted through or scattered by the sample, or fluorescent light generated from the sample is directed into a photoelectric converter via an optical system. The light radiating area of sample characteristic measuring light can be efficiently modified to improve the resolution of a light characteristic image of the surface topography and optical characteristic of the sample at high resolution, without relying on the existence of transmissivity and conductivity in the sample.
