摘要： PROBLEM TO BE SOLVED: To obtain a rod-type laser current meter by which the flow velocity of an axial flow and a lateral flow around a capillary group can be measured without being influenced by an obstacle in the circumference regarding a flow- velocity measuring place in which a flow velocity cannot be measured from the outside due to an obstacle in the circumference. SOLUTION: A spacer 10 for an insertion rod 1, a 90 deg.-optical-path conversion mirror 11 which bends a laser beam to be a right angle and a glass window 12 which prevents water from creeping and which passes a laser beam to a flow-passage position are installed inside a capillary 2 for measurement. An optical fiber probe 1a and an optical fiber probe 1b which guide a laser beam from a light emitting part and the insertion rod 1 in which a lens 1d used to cross two laser beams are inserted into the capillary 2 for measurement. The crossing part of laser beams is formed in a flow-passage position (a measuring position), and an axial flow and a lateral flow can be measured. In a state that the insertion rod 1 is inserted into the capillary 2 for measurement, it is installed inside a capillary bundle. Thereby, a flow velocity can be measured in a flow-passage part which cannot be seen from the outside.

摘要： PROBLEM TO BE SOLVED: To measure accurately the surface whose curvature center is approximately positioned on an rotation center, regardless of the size of the radius of curvature of the surface.
SOLUTION: The surface of a measuring object 100 is irradiated with laser light so that a focal point is positioned on the rotation center (an approximate curvature center of the measuring object surface) of the measuring object 100. Hereby, even in the case where the radius of curvature is small (a), or where the radius of curvature is large (b), the largest incident angle to the measuring object surface of the laser light becomes equal as shown in the figure c, and consequently the largest reflection angle becomes equal and an expansion angle of reflected light 43 becomes equal. Resultantly, the quantity of the reflected light 43 receivable by a lens optical system 71 can be equal and excellent regardless of the size of the radius of curvature of the measuring object 100 surface.

摘要翻译：要解决的问题：为了精确地测量曲率中心近似位于旋转中心的表面，而与表面的曲率半径的大小无关。解决方案：用激光照射测量物体100的表面，使得焦点位于测量对象100的旋转中心（测量对象表面的近似曲率中心）。因此，即使在曲率半径小（a）或曲率半径大的情况（b），如图c所示，与激光的测量物体表面的最大入射角度相等，因此最大反射角度相等，反射光43的扩展角度相等。因此，透镜光学系统71可接收的反射光43的数量与测量对象100表面的曲率半径的大小无关，可以是相同和优异的。版权所有（C）2007，JPO＆INPIT

摘要： PURPOSE:To improve S/N by reflecting forward dispersed light, making it enter a light measuring optical system, reflecting a first and a second laser beams which pass a spot ahead, and converging them on the spot again by chaning optical paths. CONSTITUTION:Laser beams 5, 8 which advance forward via a spot 0 become parallel in a collimator lens 21 and enter in a corner cube 23. The cube 23 folds incident light back with an optical axis L as the center and radiates it. Consequently, the laser beams 5, 8 exchange their optical paths and are radiated from the cube 23 due to the ad justment of position and direction of the optical axis L of the cube 23 to form interference stripes on the spot 0 again. If these interference stripes are heterodyne interference stripes, the direction of movement of interference stripes made by the laser beams 5, 8 in a go path and the direction of movement of interference stripes made by the laser beams 5, 8 in a return path become the same, and dispersed light ahead in the go path and dispersed light back in the return path are detected together. A signal which is high in S/N is obtained.
