The invention description (>) is correct. In addition, when the optical path difference of the fiber is too large, the number of interference fringes is also large, and the high-order interference fringes will fade, and there may be a calculation error. The subsidy measures used by Tide are Senaraont Compensator and Berek Compensator, but the compensation range of the optical path difference is too small, and it is not suitable for fibers with large optical path difference.

In addition, the rib-reinforcing measures used for measurement are also Babinet Conpensator, etc., but it is only an approximate value of the difference in light path difference, and it is not suitable for the orientation of fibers with high accuracy requirements_ set. The parallel Nicols prism rotation method is a method that requires a sheet-like uniform thickness sample orientation. It is not suitable for measuring the orientation of fibers with circular or arbitrary cross-sections. In addition, it is still necessary to use a mechanism for rotating the polarizer and the analyzer as a whole around the optical axis, a filter attaching and detaching mechanism for sequentially changing the wavelength of monochromatic light, and removing and placing the wave blocking plate in the light. The wave barrier position control mechanism on the road will have a complicated structure. The step compensator method is a majority of chirped wave retarders with different optical path differences (such as 1 / 4λ, 1 / 2fan, 1A, 2A, 3λ, 5λ >). It is not suitable for the supplementation of small optical path difference (less than 1 / 4λ). Moreover, it does not show a pair of black interference fringes when the fiber is in any cross section, so it is not suitable for the orientation of the fiber in any cross section. And the optical path difference of unstretched filaments, ultra-fine filaments, etc. is very small (less than 1/1 Q 0 and below). Therefore, when measuring with wave resistance K, it is necessary to prepare a wave resistance with a small optical path difference. Its working efficiency is very low. Therefore, the target of the step compensator method is limited to the fiber of the graphic section, and the optical path difference must also be large (1/4; 1 or more). 4- ------------ l · ^ --------- Order --------- line (please read the precautions on the back before filling this page) Standards are applicable to China National Standard (CNS) A4 specifications (210 X 297 mm).

Description of Invention (/) When R = R1, as shown in Figures 5 (c) and (d), the light in the X-axis direction and the Y-axis direction The light will become in phase. The light in the same phase cannot transmit through the rotating polarizer (52), so when the light in this state is observed, it will become dark, and a pair of black interference fringes will appear. In this state, the thickness t of the fiber is used. The birefringence ΛN can be found. That is, the birefringence, which is defined as the degree of orientation of the unitary dimension in the synthetic star wire, is obtained by dividing the optical path difference R of the transmitted light by the thickness t. Value to represent. Here, the synthetic gauze silk is not a flat plate having a certain thickness, but a round cross-section. Therefore, the thickness t of the object to be measured. The fiber diameter cannot be used, but a representative thickness 1 that can be replaced is required. Β Therefore, in a synthetic fiber filament with a cross-sectional shape that is approximately circular, if the representative thickness t and the transmitted optical path difference R are calculated, the 2 inclination value can be calculated. Then, the birefringence ΛN defined as the degree of orientation can be obtained. The foregoing is a description of the deformation of the definition formula, and the following is a description of a method for determining the degree of fiber orientation from the formula (4) using the measuring device of the present invention. Assuming that the thickness direction of the synthetic fiber filament (F) parallel to the measurement object is the X-axis direction and the length direction parallel to the y-axis direction, the inclination orientation of each constituent mechanism is arranged in such an orientation as described above. Later, it will exhibit the function of converting ellipsoidal cadmium light into linear polarized light and supplying it to a rotating polarizer. That is, by setting each constituent mechanism at a predetermined orientation, the interference color of the synthetic fiber filament (F) can be displayed, and the stepwise compensation by the wave barrier (42) and the connection by the rotating polarizer (52) can be achieved.

Description of the Invention (?) Next, when the fiber is to be placed under a microscope, a liquid having a refractive index approximately the same as the refractive index in the direction of the thickness of the fiber is used to fill the periphery of the fiber. This prevents the reed from directly contacting the atmosphere, avoids complicated refraction of light at the end of the fiber, and accurately determines the degree of orientation. Moreover, it is preferable that the direction in which Pan Wei is placed on the display mirror is such that the longitudinal direction of the strands (Z axis direction) becomes the front-back direction of the microscope. In this way, the alignment position of the fiber under the objective lens and the observation interference phenomenon can be made easier, and the coordinate axis and directivity can be easily aligned on an image processing device or the like. Then, the synthetic light wire (F) is irradiated with white light by the light source mechanism (2). Due to the use of white light, rainbow-colored interfering colors can be displayed on the image of the hybrid M. Because it shows a rainbow interference color, when using a wave retarder to compensate the optical path difference, it can be clearly determined that the wave impedance Η is to be added or subtracted β, and only when the optical path difference is completely compensated This position is the only one that will become dark. Therefore, the judgment that the compensation of the optical path difference has been completed can be made explicitly. Next, a majority of the wave retarders having different optical path difference compensation values are used to compensate the optical path difference of the fiber. The optical path difference compensation value of the wave barrier sheet is, for example, 1 to 3, 3, 9λ, ..., and the like. 1Α is a reference wavelength, and although there is no other limitation, it is ideal to use 5 4 6ηπ in terms of the periodicity and physiological wavelength sensitivity of the interference color displayed by the optical path difference. The wave retarder is used in combination with the X-axis direction or the Υ-axis direction and placed in the addition and subtraction operation notch. The Y-axis direction is additive, and the X-axis direction is subtracted. For example, when 3λ is placed in the Y-axis direction and 1λ is placed in the X-axis direction, the optical path difference compensation value becomes -1 1-This paper is also applicable to the Chinese National Standard (CNS ) A4 specification (210 X 297 mm) • ^ 1 1 ^ 1 n I nn I nt I LI (Please read the unintentional matter on the back before filling this page) A7 414814 B7_ V. Description of the invention () (3λ-1Λ ) β uses 1; 1, 3Λ, 9 and sometimes, it can form a 1λ pitch difference between 1 and 13. If you add a wave barrier that is less than 1, for example, 1 / 9λ, 1/3, and so on, you can form a 1/9 and a pitch difference between 1/9 and ~ (13 + 4 / 3Α). In order to obtain the most effective combination of wave barriers, the optical path difference compensation value of wave barriers e3m χΛ (βι = 0, ± 1, ± 2, ··) is ideal. When βι = -2, -1, 0, 1, 2 is to prepare 1/9 A, 1/3 A, 1 Λ, 3 λ, 9λ. This prevents the combination of wave barriers from repeating, and can achieve a wide range of compensation values with the minimum number of wave barriers required. When the interference color is observed by the observation mechanism (3), and the compensation value of the optical path difference of the wave blocking plate is gradually increased, the interference color will gradually shift to a low order (in the direction of the dark part). The function of the lagging R part leading R1, if adjusted to ίί = ί ′, the lagging part of the light in the direction of the y-axis will be compensated (canceled), and become as shown in Figure 5 (c), (d) Of the state. When you observe the light in this state, what you see is dark. If the fiber is a circular cross-section, a pair of black interference fringes (S) are shown in Figure 6 (b).

Description of the Invention () W: The distance between a pair of black interference fringes of a circular cross-section fiber. In this method, the degree of orientation associated with a normal circular cross-section fiber can be determined by adjusting the wave impedance Η. However, the wave retarder is a step-wise compensation optical path difference, so there is a limit to its minimum compensation value. To measure a raylet (unstretched filament or thin fiber) with a very small optical path difference (l / lfl0; L or less), it is necessary to prepare a small number of optical path differences when measuring with a wave retarder. Wave barriers are not only inefficient and uneconomical. In the case of a fiber having an arbitrary cross-section, a pair of black interference fringes does not appear, so that the formula (4) is not applicable. In this case, the compensation of the wave-resistive sheet is only limited to the coarse adjustment, and the following operations are used to compensate for the light level. "Turn the rotating radial plate (52) in the forward or reverse direction, and entangle it on one side. The compensation of the optical path difference is completely rounded to completely compensate the optical path difference and make it appear in the dark part. The light with a small optical path difference that cannot be fully compensated in the wave barrier is generally elliptically polarized. The conversion mechanism (51) has an optical path difference of 1/4 λ. When disposed in the above orientation, it has the function of converting elliptical polarized light to linear polarized light. Β This principle can be described by the Poincare sphere described in the maple light related literature and the like. (Poincare Sphere) to explain, and here will be explained in detail. The light transmitted from the conversion mechanism becomes linearly polarized light, but its polarization direction is shifted by 0 degrees. The relationship between the degree of residual light ϋ and the direction of polarized light 0 is ϋ = θ / 18 (T · λ. Therefore, when the polarization is rotated by 0 degrees, the direction of polarized light becomes orthogonal and a dark part appears. In a circular cross section 纗In the case of dimensionality, a pair of black interference fringes as shown in the S (b > circle) will appear even though the optical path difference is small.

Let the fiber thickness at the position of the η interference fringe be τη, and the successor cone at the position of the η + 1 interference fringe. When the thickness is Tn + i, the number K of interference fringes η can be verified by the formula (8). The measurement methods for τη and τη + 1 are as follows: if a circular cross section is used, the auxiliary line of the cross section can be drawn on the image processing device for measurement. In the case of Panwei with an arbitrary cross section, it can be obtained by a well-known thickness measuring device. Κ = Τη / (Tn + 1 -Tn) ..... (8) [Effect of the invention] As described in detail above, according to the present invention, it is possible to provide a low-cost orientation that is easy to prepare for measurement and easy to perform measurement. Landing device. In addition, there is a difference between the set and the difference, and the calculation can be counted as light, and it is not streaked. * The rules are related to tide. The degree of dryness is determined by the degree of accuracy and accuracy. The accuracy is determined by the obtained pairs, which can be determined in the fiber. The degree of error in the product measurement is wrong. The value of the negative dimension of the fixed value or the zero of each fiber of the sample dimension is the difference between the two, and the shape of the light is 0, and its shape is also feasible for the measurement surface, and the degree, and the simple diagram Fig. 12 3 4 BB 6 6 The texture of the image of the image of the strip is composed by the compensation of the image. The difference between the optical structure and the mechanical structure of the difference patterning process. The deflection profile of the fixed beam segment is determined to the fixed dimension m.
