JPS58139008A - Device for obtaining topographic image on surface of rotary body - Google Patents

Abstract

PURPOSE:To obtain the topographic image over the wide range of orientations of the rotary body, by irradiating rotatable pulse plane luminous flux of a laser on the rotary body through a reflector that is coaxially rotated with the rotary shaft of the rotary body, and recording the reflected light at a specified instantaneous position. CONSTITUTION:A turret assembly 8 having the rotary shaft which is aligned with the rotary shaft of a body to be checked 5 is rotated. The lasers 1 and 9, which are attached to the assembly 8, a synchronizing device 6, a light recorder 3, and a light detector 10 are positioned at specified places. When the rotating body 5 crosses the light beam from the laser 9, the reflected light from the surface is inputted into the light detector 10. Its output triggers the laser 1 through a wave shaping amplifier 11 and an AND gate 12. The pulse light from the laser 1 becomes the plane luminous flux 15 through an optical system 2 and crosses the surface of the body 15 through a reflector 17. The trace 16 of the point forms the topographic image and it is recorded in the light recorder 3. Then the turret assembly 8 is rotated and the measurement is performed at the other direction, and the procedure is repeated. Then the topographic image over the wide range of orientations of the rotary body 5 is obtained.

Description

[Detailed description of the invention]

The present invention relates to a good definition device designed for determining the surface shape of an object, and more particularly to a device for obtaining the tobograph g1 of the surface of a rotating object. Such a device can be applied in the industry - for example, when determining the deformation of an object due to the effect of a broken JIK quality control as a source of information on the shape of a workpiece. Other possible uses include when storing information about the shape of an object, such as when studying the carbonization that occurs on its surface or in its orientation in space over time. Topographic images of surface patterns are obtained by using sophisticated optical devices, and they are usually classified into holographic devices and non-holographic devices, depending on the method of changing the information of the surface pattern. Due to their relative simplicity, non-holographic methods have hitherto found a relatively wide field of use. (Non-destructive testing of holographic ivy, Academic Press, New York, London, NZ, by Mr. Elf, R.) Non-holographic methods for analyzing surface patterns include the Moiré method and! Contains 9 Tll direct projection methods. The former method basically has the following configuration. A grating is placed at near oscillation, and the creation representation is projected by the light that has passed through this grating, and the distribution of light intensity that passes through this grating increases the intensity of the light object. recorded. Such a method cannot be said to be completely successful in examining objects moving in space; after all, case 1 is 1
．． This is because the table m#IC to be examined needs to be placed next to it. If the above condition is not 1ius, the light diffraction behind the grating will write the quality of the seven-area pattern formed by the grating projection onto the surface 1 and the interference of the grating image, resulting in This is because the ill constant error increases. The well-known Tetsu-nishi, which uses the straight-line projection method, has many advantages9.

For example, it can be inspected at a close interval with iIk. One of the latter factors is xt* in a moving or corrosive medium.
Superposition is particularly useful when analyzing the shape of an object in motion (or a fixed object). The above advantage is only for objects in 1f when the research surface is in the right direction.
C. Being used as a convenience is rather unfortunate. The above limitations are inherent in the linear projection method, which involves projecting the study surface with a set of photon planes, equally spaced horizontally) and a light beam. Another 4 between the photon surface and the investigation surface! - is a constant height.Obviously, the illumination angle of the redundant surface must be as close to the grating angle as possible, t7'C, which is -fC,1ill. should be large enough to avoid dark intervals. On the other hand, the field of view and force direction of the source recorder, which indicates the distribution of light intensity on the surface to be scanned, should be overselected so that the near-focal field, which is shifted left and right by the curvature of the surface to be scanned, is minimized. be.

In the case of a laser, an optical system incorporating a lens assembly and an interference needle for forming a set of photon surfaces, and an optical recorder, the surface to be studied is intersected. area r
c is projected by two coherent beams forming the measurement volume. The interference batten within this one constant volume, lIT*I, having the maximum intensity is usually observed as an original plane. When the above-mentioned KM-field surface is manipulated into 4 planes, the line of intersection of the light plane and the survey surface forms its directional topocratus. Namely, on! Using the device of e, illumination and recording are meant to be broken down in a universal manner as explained above. Commercial operators often encounter many problems when determining the surface shape of interlocking objects that change orientation in space. A typical problem □ in this class 11 is to describe the motion, bending strain, and torsional strain of the rotor blade. In addition to the circumferential movement of the rotor's axis of rotation, the flakes move roughly around the edges, plates, and roots.
Subject to bending and screw strains. The essence of the above is the following points: Considering the shape of the surface and its positioning movement in a broader sense, the unknown characteristics of the direction that should be determined are the characteristics that are influenced by rotational movement.

The objective is to continuously facilitate the orientation and position #jL of the surface under study.

Reference jl ) is the optical system that forms the light years TkJv of the laser and - group, and 9! The recording plane of this optical record-6 is optically compatible with the surface under study. The generatrix is positioned so that it is always parallel to the optical plane m (count) which forms the topography image on the surface of the surface V. The above requirement severely limits the s1 surface of the surface being examined. In particular, it is not possible to examine an object whose axis of rotation is inclined at a certain angle with respect to the surface of the study Φ, and whose orientation with respect to the axis of rotation changes (-1). (Consider the rotational axis of the blade, etc.) Using the above-mentioned rice malt in the above case will severely reduce the constant 1m@I and reduce the measurement accuracy. This is because the *-letter is far from optimal. In order to achieve high precision and a sufficiently wide #j standard, it is important that the light-year orientation of the object under study at an arbitrary anti-angle kK should be close to the optimum. Moreover, it must be correlated to the predetermined angular position and the positioning mode. It is an object of the present invention to obtain a topograph of the surface of a rolling object over a wide range of longitudinal movement of the body and orientation of the rolling object. Toi provides high-precision equipment to obtain 1 illumination. The above object is achieved by the following equipment WltK.A device for obtaining a Tobokurafu image of the surface of an object undergoing zero rotation includes a pulse laser, an optical system for forming a light-year plane, and With an optical record i having an orientation that is optically matched to the rotating object under study, it is possible, according to the invention, to capture the laser emission moment from the rotating object or the relative plane along its path. The device is mounted on a rotating tare assembly coaxial with the rotation of the rotating object, the device being arranged so as to be synchronized at the moment of passing through the point M1. The -g axis includes an object, and the -1 axis includes a reflector that projects laser radiation onto the rotating object. By allowing the optimal orientation of a set of light-year directions at an arbitrary angle reversal of 1 of a rotating object and using the toboguthu image of the surface of the 1-rotating object. This has the advantage of increasing the accuracy and range in the -j constant of the coordinates of points on the i rolling element rRiiI. Advantageously, the synchronization in'' includes a radiation source projecting at a fixed point along the path of the rotating object and a radiation source projecting at a fixed point along the path of the rotating object.
a radiation detector which records a signal as it traces a pulsed laser beam and provides a synchronizing signal to emit a pulse laser; It is. The wheel load forming the main drive of the present invention is at an angular position kKJd
The spatial synchronization of a set of nine planes is maintained with respect to the rotation rate Ei+ of the F quantity object. - The optical system for forming the set of light-year planes can be arranged in one order on the one-rotation object. This allows real-time recording of the topography of the surface of the object during one revolution. The 11-fold grating may be omitted as an optical system forming a -set of party planes. This can significantly simplify and reduce the size of the kllc forming the - pair of light years. The focusing device may be arranged along the axis of the pulsed laser. The above characteristics are important when examining the shadow of the divergence of the pulsed laser beam on the optical thickness of the light-year plane, especially when the distance between the laser beam and the object to be scanned is large.

It includes a collimator and a cylindrical lens tightly coupled to the optical system to form a lens. This is the j of research & distribution and its b turning axis! Rotating to di maintains a constant orientation of the optical half plane with respect to the @FC study surface. A device that is designed to synchronize the intervals when an object passes through the triset point can be used to detect the moment when a rotating object passes through a predetermined angle at a predetermined angle. The sensor is connected to a clock pulse generator K)), the output of which is coupled to a pulsed laser. The above % view makes it possible to obtain a sequence of 7-images of its ostensible topography at the true angular position of the rotating object, and that sequence has a first position 8iv of preset leakage. Preferably, the synchronization device comprises a flip-flop;
Its set input is connected to the 4"F') output during the time when the rotating object passes through a predetermined angular position, and the output of the flip-flop is connected to a clock pulse generator. , connected to this clock pulse generator has a nine-input vh pulse counter, the output of which is coupled to the reset input of the flip-flop. This synchronization device uses a control 4IWl function inserted between the sensor 1 and the flip-flop to indicate the moment when the rotating object passes through a predetermined angular position. In addition to the delay line, it may also include a second pulse counter, the input of which is connected to the output of the first pulse counter, and the output of the first pulse counter is connected to the delay line of said delay line. The above features make it possible to obtain a succession of topocrats when the rotating object makes two or more flips, preferably one. i11 has 1. a unit for controlling the position of the turret assembly, the unit compares the signal with a sensor indicating the current position of the turret assembly and a sensor detecting the V reset position of the turret assembly position; In order to do this, the output of the comparator circuit is simultaneously followed by the output of the radiation detector, and the output of the comparator circuit is simultaneously A pulsed laser is activated when a signal is applied from the output of the radiation detector. The radiation source of the synchronization device is often an OW relay with a shutter, and the output of the optical path is a pulsed laser.

The research object jK has a reflection @- which projects the radiation from the laser I. a laser l, an optical system for forming a - group of light-year planes], and a synchronization device 14
The optical recorder 3 is equipped with a turret assembly that rotates once, and its rotation axis is 0. It coincides with the rotation axis of the object X to be inspected. The synchronization device t4 is a radiation source! 1 For example, O
Contains a W laser, and its radiation is a rotating object! It has a radiation detector IO, which is a photoelectric detector when using a laser, projected at a preset point along the path of the laser, and the output of the detector is sent to a shaped amplification@// and a MD gate/21. A pulsed laser 7 is coupled to the input via the pulsed laser 7. The optical axis of the pulsed laser I, the set of devices for forming a light-year plane, the optical recording fFJ, and the light source 9 and the light detector *10 of the synchronization device are preferably aligned in the light-year plane. It is located within a single intersecting plane. A rotating object! To obtain a topographical image of the surface of , the turret assembly l rotates once to assume an angular position of h. When the moving object S traverses the light beam /Jtf from the laser t, the light scattered by its surface enters the photodetector 10K,
It is converted into an electrical signal and the signal is shaped and increased.
It is normalized in t and passes through the ND gate, whose first input receives an enabling signal for the pulsed laser IJ. When the nine beams from the pulsed laser I pass through the optical system, they form a reflector on the surface of the research object S.
(Thus, a set of light-year planes ljK are transformed. The trace/6 of the intersection of the light-year plane and the surface of the object 13 creates a topograph th6 (FIG. 1), which is broken by the optical record 63. The obtained toboclave is the IIR of the object being studied (in this case, the blades of a rotor model).
I[! It has shape information. However, when he scolded him, KIg1 exploded to take another azimuth position, and it was recorded! Ikuru is criticized. Since the synchronization unit 111m is located above the turret assembly l which is turning once,
The topographic image is taken at a fixed relative position between the device for forming the set of light 's+1lIV and the reflector 7, which is a feature that improves the accuracy of the Ill determination. To form a set of light years, 11J is an interferometer (not shown) that creates two intersecting coherent optical beams.
and a lens assembly (not shown) that expands the beam to the diameter of F5Tll and focuses it in the vicinity of the research surface.
A representative beam can be conveniently obtained by an optical system consisting of and. The coherent original beams intersecting close to the scanning surface form a measurement volume consisting of -1 il light-years (Iik large interference batten). - It is proved that the exposure distribution in the plane in which the image of the scanning surface is formed, (1, ri (sugar J diagram)) is given by the following formula: I p (X, y) =I.(i +4 (w)

Therefore, use topography-1 To determine the surface shape of K, it is necessary to calculate the distribution in a constant volume and find the coordinates of the interference band on the topographic image. By checking, -1
The calculation is carried out by using an italophotometer (not shown) V and by calculating the dew W extremum locus IIIv. It was expressed as the number of koji in the interference band. The error when determining the maximum m can be obtained as follows. GO is the spectrum noise level of the Toboda Fu image l - Ba (w) = I is the Miku photometer ( The frequency response and effective frequency response of the scanning device (not shown) are determined by the area.

The error when fixing can be set to 5R as follows (if the coordinates are known and the fixed coordinates are ignored). Here, m, (i) -Ba' is defined as a function that reduces the number of empty I-Ki to a single number. Therefore, by referring to the formula (,?), it can be seen that the minimum #j constant error *vID can be calculated. The above comments indicate the necessity of selecting the same combinations of Rin and Kiyon in order to obtain high haze accuracy. The requirement is met by maintaining a constant V value between the 90° l1kllj and the optical 1c device J to the rotating object under investigation at any angular position of the rotating object. Generally, the tobog on the surface of the object that is wrapped once per night is 9ym.

Turret assembly l has 11 rolled 0 elements /7 and /
When the output signals of I become equal, the output of the comparator circuit /f generates a signal that allows the synchronization signal V to pass which triggers the pulse racer I. The output signal of the comparator circuit /9 is also used to open the shutters and the shutters, and the shutters KW1 and KW1 through which the synchronous four-da signal has passed are detected. As you can see from the explanation above, when the rotation speed is high, an object can break in one inspection! rotates several times between recording cycles. Therefore, the information on the fist movement of the object 14F at the full rotational angle can be obtained by considering that we are dealing with a dead dust elephant. On the one hand, there is such a gap that it is necessary to obtain information about the changes in the object surface and its changes. In this case, the ninth optical system forming a set of nine half-planes should be positioned on the moving and rolling object S along its axis of rotation to maintain the optimum orientation of the light-year plane. Is it true that I have it? When dealing with objects with large rotational speeds, it is essential that the gratings used to form a pair of light-year planes be compact and sturdy. It can function as an optical system. A focusing device located along the optical axis of the pulsed laser has a collimator which may be mounted on a turret assembly and a cylindrical lens placed to the side of the diffraction grating. . The pulse laser I is triggered by the clock pulse start @#, and the clock pulse generator is a one-turn object! is triggered by a signal from the sennum indicating the moment when the angle passes through a predetermined angular position 1. 1 The parameters of the collimator are selected such that the laser beam co-7 is focused in close proximity to the object under study.
The beam is transformed into each plane, and the light diffraction on the grating forms a set of light years. (Diffraction Sequence Co), [gl Diffraction In order to reduce the loss of ψ11, a phase diffraction grating can be used to reduce the damage caused by the high power pulsed radiation of the IL laser l. It is possible to obtain less vm and also a more uniform distribution of the originals within the diffraction sequence. The repetition rate of the clock pulses and their number are selected to obtain the required number of pulses to analyze the required process. If the missing process is continuous for more than one rotation of the object, it is synchronized. The converting device has a design error of 1% as shown below, and is controlled by a counting code, and a flip-flop JOV and a flip-flop JOV. !Figure) Connect the output of the delay line 7JO to the K111 column with the Vtsku pulse threat generator. 3rd output of Kuroshif pulse generation port, laser/Km continuation school, pulse counter 3 of tatasha 7

Change to 6s. When this happens, the clock pulse generator will fail and its pulse 311) will trigger the X-pulse racer and be multiplied by the first pulse 33. After the second kakunta J,) is full, the output of 4C, 7 produces a signal 39, which turns the Aritzkflora 730 into cell 1i16Ki and changes the state of the counter 3da to 1i16Ki.
The change code at the output of this second counter 3d increases the delay set by line 9 by the discontinuity of Δt(T, where V(1' is the repetition value of the clock pulse). Therefore, the next synchronization pulse l/ )'j s flip-flop 30 is set to an overvoltage of Δt, and the clock pulse is delayed accordingly.In the next calculation cycle, the clock pulse is delayed by 1 nott.
There will be a delay. The following is the same aircraft, the synchronization device is 111
Two kojis allow to record a topography on a single object during multiple rotations within one frame of the optical recording 41J. As can be seen from the above theory, if the axis of the pulsed laser I and the axis of rotation of the rolling element S under study are not relatively aligned, the light-year direction across the object's surface 1kIv will be displaced. , - produces a Kla difference when determining the shape of the object being scanned. a

To obtain the volume 3v, the optical string shown in Figure '1 is used, which forms the light-year direction of the laser beam, beam slit, mirror axis, reference 7, and - pair. The collimated beam S/ of the optical system G, the collimator 419, the holographic frame 10, and the VT beam is used as a reference beam, and the original beam of the output of the optical system etr forms the target wavefront. . The resulting hologram, when reconstructed by the collimated beam j/, is the same as that at the output of the system and the average of allm

Clearly, the reconstructed system of light-years is invariant under the relative IllIm displacement of the collimated tightly packed beam and the axis of rotation of the reeling object. - It can be used to obtain the topography of the object II. For example, VC overload is used to determine the deformation of the wing of an airplane model in the Jl tunnel, or to analyze the surface of a component with a biaxial shape that is illuminated from different @ planes. As already mentioned, the optimal j! To obtain the @light and orientation position, it is necessary to decipher the orientation of the light years. The synchronization@Kojiban built into this proposed device can temporally and spatially synchronize the orientation of the light-year plane with respect to the one-scan surface with high precision and unreasonable accuracy. . Generally, when determining the shape of the surface of an object, i.e. when analyzing the rapid process, the topography of the object surface -
