摘要:
An apparatus capable of measuring the topography and the optical characteristics of the surface of a sample at high resolution irrespective of the transmittance and the conductivity of the sample is realized. The apparatus comprises a probe, a light source for illuminating a sample with light, a photoelectric converter device and optics for receiving light transmitted through the sample or light reflected by the sample, a laser emitting laser light for detecting deflections of the probe, a condenser lens for directing the laser light to the rear surface of the probe, a detection system for detecting reflected light, a rough-motion mechanism and a fine-motion mechanism for moving the sample and the probe relative to each other, a control means for controlling the distance between the sample and the probe, and a computer for controlling the whole apparatus. The probe has a front end portion and a light-propagating body continuous with the front end portion. The front end portion and the light-propagating body are shaped like a hook. The apparatus observes the topography and the optical characteristics of the surface of the sample.

An optical probe is used in a near-field effect microscope for performing topographical observation and physical property measurement on a surface of a sample. The optical probe comprises an optical resonator having an optical fiber having at least one microscopic projection composed of a dielectric material disposed at an end portion of the optical fiber for transmitting light.

An optical probe comprises a waveguide having an optical opening for passing light therethrough, the waveguide terminating in a sharp tip at a distal end thereof. A metal film is coated on the distal end of the waveguide except for the optical opening. The metal film has a curved surface gradually retreating from the optical opening to an outer circumference of the waveguide.

There is provided an optical memory medium comprising a flat plate modified on the surface thereof by a photolytic residual group, an optical recording apparatus comprising an optical probe having a microscopic aperture on the leading end thereof, a light source, X-Y-Z position control means, and a controller for controlling the apparatus as whole and an apparatus for reading the optical memory medium comprising the optical memory medium, a friction detecting probe, an X-Y-Z position control means and a controller for controlling the apparatus as a whole. Further, information is written and read with high density less than the wavelength of light using an apparatus for writing to and reading from an optical memory piezoelectric medium comprising the optical memory piezoelectric medium constituted by a piezoelectric element modified on the surface thereof by a photolytic residual group, an optical probe having a microscopic aperture on the leading end thereof, a light source, an X-Y-Z position control means, a means for measuring the resonance characteristics of the piezoelectric element and a controller for controlling the apparatus as a whole.
摘要:
A mode switching mechanism comprises a driving toothed wheel driven by a motor, a driven wheel having first and second coaxially mounted cams for rotation therewith, a toothed circumferential portion for providing meshing contact with the driving wheel and a toothless circumferential portion for providing out of meshing contact with the driving wheel. The driven wheel is normally urged so that it comes into meshing contact with the driving wheel. A spring-biased rotatable trigger lever is arranged to lock the driven wheel in a position out of meshing contact with the driving wheel and unlock it in response to the operation of any one of tape operating mode keys to establish the meshing contact to thereby allow the driven wheel to be rotated by the driving wheel. A a first cam follower is movable to a recording/playback position by camming contact with the second cam in response to the operation of one of the recording and playback mode keys, and a second cam follower is movable to a rewind/fast-forward position by camming contact with the second cam in response to the operation of one of the rewind and fast-forward mode keys.
