摘要： The present focusing method is used in a focus detecting apparatus comprising an objective lens, means for entering a luminous flux for focus detection into a target object from a position inconsistent with an optical axis of the objective lens through at least the objective lens, a condenser lens for converging the luminous flux after it is reflected by the target object and again passes through the objective lens, two two-division sensors disposed with the same optical inclination in front of and behind a position where the reflected luminous flux is converged by the condenser lens when a focus of the objective lens is adjusted to the surface of the target object, and a signal processing circuit for performing operational processing of signals from the two two-division sensors. The focus detecting apparatus detects whether the focus of the objective lens is adjusted to the surface of the target object. When focusing is performed with this apparatus, the target object is moved while the focus position is followed after the detection of the focus position, focus detection is performed many times and the detected signal values are averaged, and the resultant average value is used to drive the objective lens. This series of operations is repeated, and then the focus position is fixed.

摘要： An optical packet header identifier having a simplified configuration and being superior in reliability, stability, and economical efficiency, an optical router incorporating the identifier therein, and a routing method using the optical router are provided. The optical packet header identifier includes an optical waveguide, optical focusing elements, and a photo receiver. Tilted gratings for diffracting an incident optical beam and emitting the beams as diffracted optical beams to the outside of the waveguide are formed within the optical waveguide. The tilted gratings are not formed uniformly in a longitudinal direction of a core of the optical waveguide, but are arranged at intervals. The length of a portion containing a set of gratings and the length of a portion containing no gratings can be defined in increments of length “L”. “L” equals to the spatial length which 1 bit in an optical signal occupies.

摘要： In laser beam scanning by a rotating polygonal mirror, a hologram scanner, etc., a cylindrical lens having a refractive power in a sub-scanning direction is introduced to place the beam deflecting surface and the scanning surface in a geometrical-optically conjugative relation, in order to prevent occurrence of a deviation in position of scanning line due to a deviation of the beam deflecting surface. However, in a Gauss beam such as a laser beam, a beam waist is not produced in a geometrical-optical conjugate point. This relation is utilized to select optical elements whereby apparatus may be miniaturized and the size of the beam spot may be adjusted.

摘要： The present invention relates to an apparatus for measuring the intracranial pressure of a living body or patient utilizing ultrasonic waves. An ultrasonic pulse is transmitted as triggered by a trigger signal into the cranium from an ultrasonic probe placed outside the cranium of the living body, the data of an interference reflection wave caused by the multiple reflections of the incident waves at the interstital boundaries within the cranium is analyzed for frequency, and the time difference between the element waves of the interference reflection wave is calculated and delivered as output. Thus, the dura mater thickness and its change are measured, and the intracranial pressure and its change can be measured utilizing the correlation between the intracranial pressure and dura mater thickness.The most of the conventional measurements of intracranial pressure are done with an invasion to the cranium, and some noninvasive techniques have been proposed but their accuracy and costs are far from the level at which they can be satisfactorily used. The apparatus according to the present invention permits to measure the intracranial pressure from outside the cranium, easily, safely, highly reliably, non-invasively and without any malinfluence on the brain inside. Furthermore, by periodically effecting such measurement, the intracranial pressure and the pattern of its change can be known and accurate diagnostic information on the pathology as well as legion-preventive information can be provided.
