Description

  The present invention relates to a cultural property inspection apparatus that inspects a cultural property by irradiating an inspection light such as infrared light or Raman excitation laser light onto a portion to be inspected of the cultural property and performing spectroscopic analysis of the reflected or scattered light. About.

In murals and paintings, or in cultural assets such as temples and shrines, historical cultural assets have been repaired as necessary due to corruption and damage over time. When restoring, it is desirable to use the same materials and paints as at the time of creation of the cultural property because of the historical background of the cultural property to be restored. Therefore, when restoring cultural properties, it is necessary to inspect, analyze, and identify the materials and paints used. In addition, when conducting research on cultural property preservation methods, research on cultural history such as the origin of materials (production areas), distribution channels, etc. ing.
When performing analysis of such cultural properties, in order to collect samples for analysis, it is often strictly limited to damage some of the valuable cultural properties. Moreover, it is desirable to perform the inspection at a place where the cultural property is installed, that is, without moving the cultural property.

Conventionally, non-destructive inspection of cultural properties has been performed using a fluorescent X-ray analysis method that performs elemental analysis using fluorescent X-rays generated when the cultural properties are irradiated with X-rays. As such a technique, for example, a technique described in Patent Document 1 (Japanese Patent Laid-Open No. 2004-340750) is known.
In Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-340750), in a measurement object constituting a cultural property, a Raman spectrum obtained by performing a Raman spectroscopic analysis on the measurement object that has been artificially altered is altered. A technique is described in which a Raman spectrum obtained by performing a Raman spectroscopic analysis on a non-measured object is evaluated for alteration. In the technique described in Patent Document 1, when confirming the material of the object of the alteration evaluation of the cultural property itself, the material is identified by the fluorescent X-ray method or the X-ray diffraction method.

JP 2004-340750 A (“0023” to “0025”, “0035”)

  The fluorescent X-ray analysis method as in the prior art can perform elemental analysis of substances constituting cultural assets, but can only analyze what elements (carbon, oxygen, nitrogen, etc.) are contained. There is a problem that structural information concerning the structure and compound of the element is poor. That is, there is a problem that it is difficult to identify pigments and the like which are constituents of cultural properties, and therefore it is very difficult to collect sufficient information regarding the origin of materials necessary for restoration or the like.

  In addition, when a cultural property is analyzed on the spot in a non-contact and non-destructive manner by Raman spectroscopy, the range and area that can be detected by Raman spectroscopy are limited. Therefore, it is necessary to determine which position of the cultural property has been detected. However, since the Raman spectrum is merely spectral information, it is difficult to specify the location. In addition, it is possible to use a Raman image that displays the intensity of the Raman spectrum two-dimensionally for a specific wavelength, but the Raman image and the actual visible image are almost the same, There is also a problem that it is difficult for a user such as a researcher to determine which position a Raman image is.

In view of the above-described circumstances, the first technical problem of the present invention is to inspect and analyze the chemical properties of the material of the cultural property without moving the cultural property in a non-contact and non-destructive manner.

The movable gantry 2 has a plurality of leg portions 2a, and a moving caster 2b with a stopper is supported at the lower end of the leg portion 2a. A handle portion 2c is supported at the upper end of the leg portion 2a so as to be movable up and down.

A rotation mechanism and a tilt mechanism (not shown) are supported on the upper portion of the handle portion 2c. Note that a conventionally known mobile gantry can be used as the mobile gantry 2. For example, a mobile gantry for moving a camera for television photography can be used.
Therefore, the movable gantry 2 can be roughly adjusted by moving the cultural property inspection apparatus 1 in the horizontal direction with respect to the fixed cultural property by moving it with the caster 2b. In addition, the height of the cultural property can be roughly adjusted by adjusting the height in the vertical direction, and the rotation position and tilt can be adjusted by the rotation mechanism and the tilt mechanism.

An excitation laser input port 4b is formed at the upper end of the case 4a, and a lens opening 4c is formed on the cultural property B side of the case 4a. An optical fiber (not shown) is connected to the excitation laser input port 4b, and an excitation laser for Raman spectroscopy is input from an external laser light source via the optical fiber. In Example 1, a laser beam having a wavelength of 785 nm is used as the excitation laser beam, but an excitation laser beam having a wavelength of visible to near infrared can be used, and may be arbitrarily selected depending on the design, specifications, and the like. Can be changed.

FIG. 3 is an explanatory diagram of a mural and an inspected part as an example of a cultural property.
In FIG. 2, an excitation laser collimator 6 for making the excitation laser beam parallel light is disposed below the excitation laser input port 4b. A reflection optical system 7 that reflects the collimated excitation laser is disposed below the excitation laser collimator 6. An edge filter 8 is disposed behind and obliquely above the reflection optical system 7. The edge filter 8 reflects light having the wavelength of the excitation laser light reflected by the reflection optical system 7 and transmits light having a wavelength shifted from the wavelength of the excitation laser light to the longer wavelength side due to the Raman effect or the like. It is a conventionally well-known filter. Instead of the edge filter, it is also possible to use a notch filter having a property of transmitting light having a wavelength shifted from the wavelength of the excitation laser light in either the long wavelength side or the short wavelength side.
2 and 3, in front of the edge filter 8, the excitation laser beam reflected by the edge filter 8 is condensed and irradiated on the inspected part B1 of the cultural property B, and the Raman from the inspected part B1. A macro measurement objective lens 9 through which light passes is arranged. In FIG. 2A, a micro measurement objective lens 11 having a narrower inspection area than the macro measurement objective lens 9 is disposed on the side of the objective lens 9, and the macro measurement objective lens 9 is manually or automatically. By moving the micro measurement objective lens 11 to the position (sliding in the left-right direction), the inspection target region can be changed.

  On the side of the reflective optical system 7 and the edge filter 8, a color CCD camera 12 for measuring area monitoring, which is an example of a visible image capturing device, is disposed. A measurement area monitoring optical system 13 having a half mirror 13a and a half mirror 13b is disposed between the measurement area monitoring CCD camera 12 and the edge filter 8 and the like. Is irradiated with illumination light from the illumination 14 composed of white LEDs. The measurement area monitoring optical system 13 is moved manually or automatically so as to be interrupted between the edge filter 8 and the macro measurement objective lens 9, whereby the light of the illumination 14 is transmitted by the half mirror 13a and the half mirror 13b. The reflected image is irradiated onto the inspected part B1, reflected light is reflected by the half mirror 13b, transmitted through the half mirror 13a, and imaged by the color CCD camera 12 for measurement area monitoring, so that a visible image of the inspected part B1 is obtained. In addition, the Raman excitation area of the laser beam can be imaged in color. In Example 1, a 3.33 mm square area is set as the inspected part B1, and the color CCD camera 12 for measuring area monitoring has a size of 7.11 mm × 5.35 mm with the inspected part B1 as the center. It is set so that a visible image of the area can be captured.

In FIG. 2, a condensing optical system 15 that condenses the light transmitted through the edge filter 8 is disposed behind the edge filter 8. The Raman light scattered by the laser beam in the inspected part B1 of the cultural property B is condensed by the condensing optical system 15, passes through the aperture 16a of the aperture 16, passes through the optical system 17, and is spectrally separated. It is introduced into a conventionally known LCTF (Liquid Crystal Tunable Filter) 18 as an example of the unit. On the other hand, most of the excitation laser light reflected and scattered by the inspected part B1 of the cultural property B is reflected by the edge filter 8, and the incidence to the optical system after the condensing optical system 15 is blocked.
In the first embodiment, an edge filter 19 is disposed on the light input side of the LCTF 18 in order to promote the attenuation of the excitation laser beam.
The Raman light having a predetermined wavelength that is spectrally separated and output by the LCTF 18 is collected by the imaging optical system 21 and is supported on the rear surface of the case 4a, and is a high sensitivity CCD camera for Raman measurement as an example of a Raman image pickup device. The image is taken at 22. The high-sensitivity CCD camera 22 for Raman measurement according to the first embodiment is configured by a high-resolution camera that can shoot by dividing the inspected part B1 into 128 × 128 regions (pixels). In Example 1, the high-sensitivity CCD camera 22 for Raman measurement is inspected so that a Raman image can be taken due to the focal length of the macro measurement objective lens 9 and other optical systems 15, 17, and 21. An area of 3.33 mm square is set as the area of the part B1.

  1 and 2A, a high resolution color CCD camera 26 as an example of a visible image pickup device is fixedly supported on the side surface of the case 4a. The high resolution color CCD camera 26 includes a high resolution zoom lens 27 for enlarging a visible image, and an illumination 28 composed of a white LED provided at the tip of the zoom lens 27. The high-resolution color CCD camera 26 can capture a visible image of an area including the inspected part B1 irradiated with light from the illumination 28. In FIG. 3, the high-resolution color CCD camera 26 according to the first embodiment is set to be capable of capturing a visible image in the visible image capturing area B2 of 10.5 mm × 7.9 mm.

  In Example 1, the high resolution CCD camera 26 is composed of a color CCD camera having one pixel (one pixel) of 14 μm square, and the high sensitivity CCD camera 22 for Raman measurement has a pixel of 26 μm square. It is composed of a monochrome CCD camera. 4A, the magnification of the zoom lens 27 is adjusted and set so that the 2 × 2 four pixels 26a of the high-resolution CCD camera 26 correspond to one pixel 22a of the high-sensitivity CCD camera 22 for Raman measurement. ing. That is, the four pixels 26a of the visible image captured by the high resolution CCD camera 26 and one pixel 22a of the Raman image of the high sensitivity CCD camera 22 for Raman measurement are associated with each other on a pixel basis.

FIG. 4 is an explanatory diagram of a setting method for one direction of the camera of the first embodiment, FIG. 4A is an explanatory diagram of the correspondence between the pixels of two types of CCD cameras, and FIG. 4B is an accurate image size and position of the reference pattern. FIG. 4C is a diagram illustrating the positional relationship between the pixel and the reference pattern, and the signal intensity. FIG. 4C illustrates the positional relationship between the pixel and the reference pattern and the signal strength when the position is not accurate or when the image size of the reference pattern is not accurate. FIG.
In order to precisely and accurately align the four pixels of the high resolution CCD camera 26 and one pixel of the high sensitivity CCD camera 22 for Raman measurement, first, the reference pattern Mk is adjusted by the high sensitivity CCD camera 22 for Raman measurement. Take a picture. Here, the reference pattern Mk is obtained by projecting an equally spaced black and white pattern onto the observation surface, and its size can be varied by a projection optical system.

  As shown in FIG. 4B, when the image magnification of the projection optical system is accurately adjusted and the positional relationship between the Raman measurement high-sensitivity CCD camera 22 and the reference pattern is accurately adjusted, as shown in the pixel 22a, The pixel with the black reference pattern Mk1 imaged has the smallest amount of incident light, and the pixel with the white reference pattern Mk2 imaged has the maximum amount of incident light. This intensity pattern is obtained in the entire measurement pixel area. If the position deviates from the position shown in FIG. 4B, the amount of light incident on each pixel is between the maximum value and the minimum value obtained in FIG. 4B as shown in the pixel 22a in FIG. descend. This intensity pattern is obtained over the entire area of the measurement pixel. On the other hand, when the image magnification of the projection optical system is not accurate and the interval between the black and white patterns is different from the pixel interval of the high sensitivity CCD camera 22 for Raman measurement, for example, as shown in FIG. In addition, although the contrast can be clearly confirmed, since the positions of the pixel and the monochrome pattern are shifted at the end portion, as shown in the pixel 22a in FIG. Therefore, by analyzing the imaging signal of the Raman measurement high-sensitivity CCD camera 22 in the entire imaging area, each pixel of the Raman measurement high-sensitivity CCD camera 22 and the black-and-white pattern (reference pattern Mk) appropriately enlarged in image are obtained. It is possible to adjust the positional relationship accurately.

Next, adjustment of the high resolution CCD camera 26 is performed with the reference pattern Mk while maintaining the projection image magnification used in the adjustment of the high sensitivity CCD camera 22 for Raman measurement. In this case, in order to adjust the image size of the reference pattern to the pixels of the high resolution CCD camera 26, a zoom lens 27 attached to the high resolution CCD camera 26 is used. When the size and position of the two pixels of the high-resolution CCD camera 26 can be accurately adjusted to the monochrome pattern Mk as shown in the pixel 26a in FIG. 4B, the intensity of each pixel 26a is 50% duty that repeats the maximum and the minimum every two pixels. Indicates a rectangular pattern. If the adjustment cannot be made accurately, for example, as shown by a pixel 26a in FIG. 4C, the pattern changes to a waveform having a different intensity in each pixel. Therefore, the positional relationship between each pixel 26a of the high resolution CCD camera 26 and the reference pattern Mk appropriately enlarged by the zoom lens 27 is accurately analyzed by analyzing the imaging signal of the high resolution CCD camera 26 in the entire imaging area. It is possible to adjust.
With the above operation, each pixel of the high-sensitivity CCD camera 22 for Raman measurement and the high-resolution CCD camera 26 can accurately adjust the positional relationship between them by using the reference pattern Mk.

So far, the adjustment for one direction has been described, but the other directions can be adjusted in the same manner. In general, since the optical magnification is constant in any direction, adjustment in both directions can be performed by adding only the position adjustment in the other direction.
In the first embodiment, a case where 2 × 2 4 pixels correspond to 1 pixel is exemplified, but the present invention is not limited to this. For example, 3 × 3 9 pixels and 1 pixel are associated with each other. It is also possible to correspond to the number of pixels. When the black and white width of the (reference pattern) Mk deviates from, for example, 1: 1, the positional relationship between the pixels of the high resolution CCD camera 26 and the high sensitivity CCD camera 22 for Raman measurement is within one pixel. Inaccuracy in position is born, but general use is often sufficient and can be employed.

  In FIG. 2A, the center between the center of the visible image photographing area B1b of the high-resolution color CCD camera 26 and the center of the photographable area B1a of the macro measurement objective lens 9 is centered in the horizontal direction (X direction). It is separated by a distance L1. Therefore, after the visible image is captured by the high resolution color CCD camera 26, the region captured by the high resolution color CCD camera 26 and the region captured by the macro measurement objective lens 9 are moved by the distance L1 between the centers. Can be combined. In addition, by moving the XY stage further in the X, -X or Y, -Y direction by a 3.33 mm square shooting area of the Raman image, a wider area was shot with the high resolution color CCD camera 26. It is possible to make the area correspond to the area photographed by the macro measurement objective lens 9.

In a state where the position of the spectroscopic analyzer 4 is roughly adjusted, the cultural property inspection program AP1 is started, and the position adjuster 3 is controlled while viewing the visible image display part G1a, so that the spectroscopic analyzer 4 for the inspected part B1 Can be fine-tuned. At this time, the Raman image shooting area display image G1g is displayed in a square frame on the visible image display portion G1a of the main image G1, and the position where the user wants to take a Raman image is adjusted. The user can easily determine whether or not they match.

To do. When the light from the part B1 to be inspected passes through the edge filters 8 and 19, reflection or scattered light of the excitation laser light is blocked, and only Raman light passes through and enters the LCTF 18. In the LCTF 18, the light is split (filtered), and only light having a predetermined wavelength is output, and the Raman image image R 1 is picked up by the high sensitivity CCD camera 22 for Raman measurement. The wavelength transmitted through the LCTF 18 is automatically shifted to a specified value every time an image is taken, and a Raman image R1 for each wavelength is taken. The photographed Raman image R1 is stored in correspondence with the visible still image G1.

Therefore, the captured Raman image R1 can be processed to obtain a Raman spectrum R2 (see FIG. 7) at a specific position of the cultural property B and displayed on the display H2. The position of the cultural property B can be easily determined and recognized by referring to the visible still image G1a. As a result, the chemical property of the cultural property B can be determined by using the Raman spectrum R2 as compared with the case of performing elemental analysis using X-rays. For example, the surface of the inspected part B1 of the cultural property B can be identified. The amount of moisture and impurities contained in the material can also be specified.
Thereby, for example, by collecting Raman spectrum data in advance for each material type and production area, storing it in a database, and comparing it with the obtained Raman spectrum R2, a mural as an example of the cultural property B can be obtained. It is possible to specify the type and place of production of the drawn material. When conducting research, restoration, or preservation of cultural history such as the origin of cultural property B, it is possible to use any material paint, even if it is the same color paint. It can be judged whether it is desirable to use it. Similarly, regarding the cultural property B other than the mural, for example, the Raman spectrum R2 of a pillar such as a shrine or a Buddhist temple is obtained and compared, whereby the material and the period can be specified.
