摘要:
An optical prove for detecting or irradiating evanescent light is manufactured by forming a film having a regulated film thickness on a substrate, then forming a recess from the rear surface of the substrate, and forming a through hole in the film from the side of the recess by etching. The obtained optical probe has a micro-aperture at the tip of the through hole and usually, a plurality of optical probes each having a micro-aperture of uniform profile are formed on a single substrate. In the recess, light-receiving or light-irradiating means may be provided.

A probe with a micro-projection for a near-field scanning optical microscope (NSOM) which comprises a substrate, first and second junction layers which are arranged on the substrate and electrically isolated from each other and which are made of an electroconductive material, and a micro-projection bonded to the substrate by way of the first and second junction layers and having a cavity in the inside. The micro-projection has first and second material layer made of different respective materials and laid one on the other to form a junction interlayer therebetween. The first and second material layers are electrically connected to the first and second junction layers respectively and independently.

A cantilever unit comprises a cantilever for supporting a probe and a displacement amount detecting means, the displacement amount detecting means being integrated with the cantilever. An information processing apparatus comprises the cantilever unit and optionally an information recording medium stationed in close vicinity to the unit, wherein an information in the medium is reproduced at a signal on the basis of an displacement amount of the cantilever. An atomic force microscope and magnetic force microscope comprise the cantilever unit, respectively.

The tiltable-body apparatus including a frame member, a tiltable body, and a pair of torsion springs having a twisting longitudinal axis. The torsion springs are disposed along the twisting longitudinal-axis opposingly with the tiltable body being interposed, support the tiltable body flexibly and rotatably about the twisting longitudinal axis relative to the frame member, and include a plurality of planar portions, compliant directions of which intersect each other when viewed along a direction of the twisting longitudinal axis. A center of gravity of the tiltable body is positioned on the twisting longitudinal axis of the torsion springs.

摘要:
There are provided a small optical deflector that can be driven at a high speed with a low voltage, provides a large angle of deflection, has a low distortion even in high speed operation and has a high static flatness of a reflective surface, and a method of producing the optical deflector. The optical deflector drives a movable plate relative to a supporting substrate to deflect a light incident on a reflective surface and has a configuration in which at least two recesses are formed in a surface of the movable plate on which the reflective surface is not formed, and a magnetic material is provided in the recesses.
