As shown in the figure, a photocuring resin 1 is placed in a case 2 equipped with a window 13 that can transmit light with a wavelength that causes the photocuring effect, and an image of an object 10 attached to a support 8 is formed by the lens 3. The lens 3 is adjusted using the position adjustment device 11 so that the focal plane 4 is formed in the photocurable resin 1. Also, the dry ice 12 is pressed against the bottom plate 7 by the spring 6,
To constantly cool a photocurable resin 1. Furthermore, a blower device 9 is also attached so that strong wind can be constantly sent to the surface of the window 13.

とができる。(e) Effect When the surface of the subject 10 attached to the support 8 is uniformly illuminated by the illumination device 14 capable of emitting light with a wavelength that has a photocuring effect, the photocurable resin 1 has a photocurable effect. Since it absorbs light of a certain wavelength, the light becomes weaker as it goes deeper into the photocurable resin 1, and the photocurable resin 1 closest to the window 13 of the case 2 begins to harden first. .
Subsequently, as time passes, the photocurable resin 1 that is further away from the window 13 also hardens, but due to the absorption of light by the photocurable resin 1, the further the light goes into the interior, the more the light becomes hardened. The strength becomes weaker. However, on the other hand, since it approaches the focal plane 4, it does not weaken so rapidly, and up to the focal plane 4, it hardens relatively smoothly. However, beyond the focal plane 4, the intensity of the light rapidly weakens due to both the diffusion of the light and the absorption of the light by the photocuring resin 1. Therefore, the photocurable resin 1 can be cured in a shape that substantially follows the focal plane 4.

ることはない。 Also, from the bottom of case 2, dry ice 12
As a result, the photocurable resin 1 is constantly cooled through the bottom plate 7, and the viscosity of the photocurable resin 1 is extremely high. The carefully formed image is not disturbed, and since the surface of the window 13 is constantly blown with strong wind by the blower 9 and is dry, the surface of the window 13 is kept dry due to the temperature difference.
The surface will not become cloudy or water droplets will adhere to the surface.
以上の理由により、丁度像の焦点面４のところ
まで硬化したところで、被写体１０への照明をや
めれば、被写体１０のレンズ３の像が、立体像の
形で取り出すことができる。 For the above reasons, if the illumination of the subject 10 is stopped when the image has hardened to the focal plane 4, the image of the subject 10 through the lens 3 can be taken out in the form of a three-dimensional image.

Attach a fused silica window as window 13 to case 2 using HILOCK UV (590). 1st
As shown in the figure, fill the photocurable resin 1 until it comes into close contact with the window 13, being careful not to introduce air bubbles into the photocurable resin 1. Then, the position of the lens 3 is adjusted by the position adjustment device 11 so that the focal plane 4 of the image of the object 10 attached to the support 8 by the lens 3 is located as close to the window 13 as possible inside the case 2. Also, dry ice 1
2 is pressed against the bottom plate 7 by a spring 6. Further, the blower device 9 constantly sends strong wind to the surface of the window 13 to dry it and prevent the surface of the window 13 from becoming cloudy. Next, by uniformly illuminating the surface of the subject 10 using an ultraviolet lamp as the illumination device 14, a three-dimensional image is created in the form of a window 13. In addition, here used as photocuring resin 1
HILOCKUV (590) has elasticity, so if you peel off this 3D image from the window 13 with something like a spatula, you can use the window 13 repeatedly.

またげられることはない。Embodiment 2 FIG. 2 shows another embodiment of the anti-fog device, in which a window 13 is slightly surrounded and an aqueous solution of ethyl alcohol is placed therein as the liquid 15. Then, since ethyl alcohol has a low melting point and can easily mix with water, water droplets formed due to the temperature difference with the surrounding air are constantly absorbed into the aqueous solution of ethyl alcohol. It doesn't get cloudy. Furthermore, since ethyl alcohol easily transmits ultraviolet rays having wavelengths that cause photocuring, image formation is not hindered by this.
