摘要:
A photographing apparatus comprises a plurality of optical image pickup units which converges object light and forming an optical image on a focus plane of an image pickup device and an image forming unit which forms a plurality of photographed images from optical images formed by the optical image pickup units. The optical axes of the optical image pickup units cross at one point near lenses, the optical image pickup units are disposed at an equal distance from the cross point, and the optical axes are set at a predetermined angle in such a manner that photographing fields of adjacent optical image pickup units are made contiguous with each other.

Information detecting apparatus comprises a probe arranged to face an information medium so as to relatively move to the information medium with thereby detect information thereon, a first vibrating device for vibrating the probe relative to the information medium in a first direction parallel with the information medium, and a first movement detecting device for detecting a state of relative displacement of the probe for the information medium in the first direction on the basis of information obtained by the probe which is caused to vibrate by the first vibrating device. A second vibrating device vibrates the probe relative to the information medium in a second direction which is parallel with the surface of the information medium and crosses the first direction, and a second movement detecting device detects a state of relative displacement of the probe with the information medium in the second direction on the basis of information obtain by the probe which is caused to vibrate by the second vibrating device.

Information is recorded by providing a recording medium having a recording layer on an electroconductive substrate transmitting an electromagnetic wave and an electroconductive optical probe arranged proximate to the recording medium, and applying a voltage between the substrate and the optical probe. The recorded information is read by irradiating an electromagnetic wave, preferably with a plurality of wavelengths, on the recording layer from the substrate side, and detecting with the optical probe an electromagnetic wave oozed out on the surface of the recording layer.

A cantilever type probe comprising a piezoelectric bimorph cantilever containing a piezoelectric material provided between driving electrodes for driving a cantilever, a probe formed thereon and a drawing electrode for a probe provided along the surface where a probe is formed, wherein there is provided a shielding electrode for electrically isolating the probe and the drawing electrode from the driving electrodes.
摘要:
A measuring arrangement includes forming first and second pairs of light beams each having a low frequency light beam and a high frequency light beam. Both pairs of light beams generate beat signals of the same frequency. The low frequency light beam of either pair and the high frequency of the other pair pass through a predetermined optical path to cause phase changes in the same direction. Beat signals are generated by superposing the first and second beam pair to provide measurement information on the phase changes.

A method of access of a probe electrode to a recording medium having on the surface thereof an edge portion having a level difference larger than a recording recess-projection or having an electron state different from a recording electron state includes steps of detecting the edge portion; causing the probe electrode to scan at a certain angle to the edge portion; and moving the recording medium in a direction along the edge portion. A method for processing information including recording, reproducing, and erasing of information by access of a probe electrode to a recording medium having on the surface thereof an edge portion having a level difference larger than a recording recess-projection or having an electron state different from a recording electron state includes steps of detecting the edge portion; causing the probe electrode to scan at a certain angle to the edge portion; and applying a pulse voltage for recording, or erasing, or a bias voltage for reproducing information between the recording medium and the probe electrode.
