摘要： PURPOSE:To obtain a measured result stable over a long period of time by obtaining a measured value, wherein the variation of a circumferential condition is corrected, by subtracting the deviation data of a reference master from that of an object to be measured. CONSTITUTION:A reference 8 to be used has material quality and a wire diameter almost same to those of an object 5 to be measured and is arranged between lenses 3, 4. In this case, the object 5 to be measured and the master 8 are arranged in parallel so as not to become shadows each other. Deviation is caused by the thermal expansion or contraction of the object 5 to be measured or master 8 according to circumstances but, for the most part, by the mechanical distortion, expansion and contraction of the first measuring systems 3-7 and the second measuring systems 11-14 or the output variation of a light source 1, the intensity of beam and the variation of the center of gravity. Therefore, by subtracting the deviation of the master 8 from the measured result of the object 5 to be measured, the correct measured value of the object 5 to be measured can be calculated.

摘要： PURPOSE:To improve a stability for a measuring value by using a single polarizing laser with a stabilized frequency as a light source. CONSTITUTION:The single polarizing laser with the stabilized frequency, e.g., a frequency stabilized He-Ne laser for the single polarizing oscillation is used as the light source 18. Luminous fluxes of the laser 18 oscillated by a power source 16 for the laser are transmitted to a rotary mirror 3 through a mirror 6. This rotary mirror 3 is provided on a driving system 2 and driven by a driver 1, thereby the luminous fluxes are deflected in an internal of 11-11A and made to be the parallel luminous fluxes 12-12A through a lens 13. These parallel luminous fluxes 12-12A are orthogonally crossed with an axis direction of a columnar object 7 to be inspected, by which interrupted in the time interval proportional to the outside diameter, then transmitted to a detector 9 through a condensing lens 8 and an aperture 17. A photoelectric conversion is made for an output signal of this detector 9, and the signal is transmitted to a signal processing circuit 14 through an amplifier 10. In this circuit 14, an edge is detected by the beam which is interrupted with the object 7 to be inspected, and the outside diameter of the object 7 is obtained by means of counting a clock pulse for the edge interval.

摘要： PURPOSE:To simplify the constitution of an optical system by knowing a distance between a beam waist position and an object to be measured from a rise or fall time of a detected signal, and knowing a position relation before and behind the object to be measured from a scattered light of the object to be measured. CONSTITUTION:When an object 6 to be measured is separated from a beam waist position, the beam diameter which intersects the object 6 to be measured becomes large, therefore, a rise of a signal outputted from a photodetector 5 is varied as a broken line from a full line. When the beam is varied by a distance without varying a distribution state in accordance with an expression I, for instance, like an interval extending from 10 to 90%, it is known by a calculation that an interval corresponding to some prescribed ratio of power is proportional to a beam diameter W. As shown clearly in the expression I, when a distance X is fixed, the beam diameter W is fixed respective of a distance in the scanning direction. Accordingly, the distance X in the optical axis direction is known from the time (t) irrespective of the position in the scanning direction of the object 6 to be measured. In such a way, the constitution of an optical system is simplified.

摘要： PURPOSE:To evade the problem of the congestion of operation such as wiring switching and to reduce the size of the device on the whole by providing connection members which are provided at end parts of terminal main bodies and are coupled by approaching each other by the movement of support members to connect optical fibers. CONSTITUTION:A driving means 8 operates to slide the 1st and 2nd terminal main bodies 14 and 24 along 1st and 2nd support members 13 and 23, and then the connection members 16 and 25 provided on those terminal main bodies 14 and 24 are positioned concentrically. Then a support member driving means 8 is put in operation to move at least one connection member 16 forth or back together with the support member 13 and connect it to the opposite connection member 25, thereby coupling the optical fibers 15 and 26 fixed to the connection members 16 and 26 with each other. Further, grip driving means 21 and 31 which constitute the driving means operate to grip operation rods 18 and 28 provided to the terminal main bodies 14 and 24 and the terminal main bodies 14 and 24 are moved along the support members 13 and 23. Consequently, the extremely easy and speedy terminal coupling is realized by the small-sized, simply constitution.

摘要： PURPOSE:To enable a stable positioning state by deforming the pin contacting part of a pin pressing member in conformity with the shape of a positioning pin and changing section-directional point contact into surface contact. CONSTITUTION:An optical switch is equipped with the positioning pin 4 which is fixed to a fixed-side switching element 2, the fiber fixation chip 12 of a moving-side switching element 3 where a 1st positioning groove 17 which engages the positioning pin at a stationary position and a 2nd positioning groove 18 which engages the positioning pin at a switching position are provided partially, and an energizing means 9 which energizes the positioning pin to each positioning groove relatively. Then the pin pressing member 10 which has a lower elastic coefficient than the positioning pin 4 is interposed between the operation part of the energizing means 9 and the positioning pin 4 and energized relatively by the pin pressing member 10. The pin pressing member 10 deforms slightly to form a hollow that the positioning pin 4 is adhered. Consequently, the positioning with stability becomes possible with the simple structure without spoiling the accuracy of optical path switching.

摘要： PURPOSE:To enable high-accuracy positioning without any influence of a clearance by arranging optical fibers and guide pins in contact with the internal surfaces of respective grooves. CONSTITUTION:A cover plate 12 is joined with and formed integrally across an adhesive layer, etc., on a guide groove substrate 11 which has optical fiber guide grooves 13 and guide pin grooves 14 formed by grinding, etc., in the top surface of an optical fiber coupling member 10. Namely, the optical fibers 1 and guide pins 2 are positioned in the optical fiber guide grooves 13 and guide pin grooves 14 of the optical fiber coupling member 10 while pressed down. Then the optical fibers 1 contact the internal surfaces of the optical fiber grooves 13 at points A and A', and the guide pins 2 contacts the internal surfaces of the guide pin grooves 14 at points B and B'. A shift in the position of the center of an optical fiber axis affects the position of an optical fiber guide groove 13 by variance in the diameter of the optical fiber 1 and the clearance between an optical fiber hole and the optical fiber is not affected at all.
