[0016] Hereinafter, examples of embodiments of the present invention will be described with reference to the accompanying drawings. The following description of the effects is one aspect of the effects of the embodiments of the present invention, and is not limited to those described here. Furthermore, the content described as an example of one embodiment may be omitted in other embodiments. Furthermore, the description of operations and processes unrelated to the characteristic parts of each embodiment may be omitted. The order of each process constituting the flowcharts described below is random as long as no contradictions or inconsistencies occur in the process content.
[0017] [First embodiment] In the following, as a first embodiment, a system including an imaging unit, a light emitting unit, and an irradiated object that can transmit visible light will be described as an example.
[0018] [system] 1 is a block diagram showing the configuration of a system according to at least one embodiment of the present invention. As shown in FIG. 1(A), the system 1 includes a light-emitting unit 2, an image capturing unit 3, an irradiated object 4, and carbon dioxide 5 having a predetermined concentration.
[0019] The light emitting unit 2 has a function of emitting light rays toward the irradiated object 4. The light emitting unit 2 may be a light source, and the light source is not particularly limited as long as it produces the effects of the present disclosure.
[0020] The imaging unit 3 has a function of capturing an image of light reflected by the irradiated object 4 (reflected light). That is, the imaging unit 3 is preferably disposed in a position where it can capture an image of the reflected light from the irradiated object 4. Examples of the imaging unit 3 include a digital camera and a camera function of a mobile phone. It may also be a wearable device. Furthermore, the imaging may be a still image or a video.
[0021] The irradiated object 4 is preferably capable of transmitting the visible light emitted from the light emitting unit 2. It is also preferably capable of reflecting the visible light emitted from the light emitting unit 2.
[0022] When conducting an experiment, it is preferable that the angle of the light beam emitted from the light emitting unit 2 and reflected by the irradiated object 4, i.e., the angle of the light beam captured by the imaging unit 3, is a predetermined angle θ from the horizontal direction, as shown in Figure 1(A) and Figure 1(B) described below.
[0023] Carbon dioxide 5 only needs to be present at a predetermined concentration or higher, and since it is a gas, it only needs to exist as a carbon dioxide region. It is also preferable that the carbon dioxide region exists so that visible light emitted from the light-emitting unit 2 and transmitted through the irradiated body 4 can pass through.
[0024] 1(B), the system 1 may include a light-emitting unit 2, an imaging unit 3, an irradiated object 4, carbon dioxide 5 at a predetermined concentration, and a storage unit 6. The light-emitting unit 2, the imaging unit 3, the irradiated object 4, and the carbon dioxide 5 are the same as those described above, and therefore will not be described here.
[0025] The storage section 6 has a function of enclosing the carbon dioxide 5. The storage section 6 may be, for example, a resin bag, but is not limited to this. Furthermore, the storage section 6 is preferably structured so that the irradiated object 4 can be placed therein so that the angle at which the light emitted from the light-emitting section 2 is reflected by the irradiated object 4 is θ. In other words, the storage section 6 is preferably structured so that one end of the irradiated object 4 is positioned inside the storage section 6. It is sufficient for the storage section 6 to contain the carbon dioxide 5, and it is preferable that the concentration of carbon dioxide differs between the inside and outside of the storage section 6.
[0026] The flow of system 1 will be explained. First, each component is arranged as shown in Figure 1(A) or Figure 1(B). First, light emitted from light emitting unit 2 hits irradiated object 4. Since irradiated object 4 is arranged at a predetermined angle θ, the irradiated light is separated into reflected light and transmitted light. The reflected light (reflected light) is imaged by imaging unit 3. The transmitted light passes through the carbon dioxide 5 region.
[0027] It is preferable that the irradiated object 4 be in contact with carbon dioxide 5. In this way, the color change can be more distinct.
[0028] [Specific example] An experiment actually conducted by the inventor will be described below. As a specific example of the system 1, the light-emitting unit 2 is a fluorescent light fixture, the imaging unit 3 is a smartphone camera, the irradiated object 4 is a eyeglass lens, the carbon dioxide 5 is evaporated dry ice, and the storage unit 6 is a plastic bag.
[0029] The fluorescent lamp fixtures used for the light-emitting unit 2 were a Panasonic Pallook Premier 40-type 38-watt, natural color, and a Panasonic Pallook Premier 32-type 30-watt, natural color.
[0030] One was a smartphone (iPhone (registered trademark) 14-128W model) used as the imaging unit 3. The other was a digital camera (OM Digital Solutions, OM SYSTEM TG-7).
[0031] An eyeglass lens was used as the irradiated object 4. The eyeglass lens used was a product name: Winvale UP1.67AS, outer diameter 80 mm, UV, clear lens, category 0, SRC2 UVP, center thickness 1.1 mm, lens material: plastic.
[0032] The reflective side of the eyeglass lenses, that is, the surface facing the light emitting unit 2 (light source), is treated with UV protection.
[0033] 20 g of dry ice was used as carbon dioxide 5. 20 g of dry ice was vaporized to obtain gaseous carbon dioxide 5.
[0034] A resin bag was used as the storage section 6. 20 g of dry ice was placed in the resin bag and evaporated to fill it with carbon dioxide. The concentration of carbon dioxide was 70% or more.
[0035] [Experimental environment 1] <Start> November 25, 2023 16:14, temperature 17℃, humidity 52% <End> Same day, 16:43, temperature 17.2℃, humidity 53%
[0036] The angle θ, which is the inclination of the light emitted from the light-emitting unit 2 and reflected by the irradiated object 4 when viewed from the horizontal direction, is set to 135°±20°. In other words, the angle between the angle of incidence and the angle of reflection from the light-emitting unit 2 is 25° or more and 65° or less.
[0037] 2A and 2B are diagrams showing the results of capturing images using a smartphone camera function, corresponding to at least one embodiment of the present invention. Fig. 2A is an image captured in the absence of carbon dioxide 5 and storage unit 6. On the other hand, Fig. 2B is an image captured in the presence of carbon dioxide 5 and storage unit 6.
[0038] As shown in Figure 2A, the reflected light was magenta, whereas in Figure 2B, the reflected light was white instead of magenta.
[0039] 3A and 3B are diagrams showing the results of imaging using a digital camera according to at least one embodiment of the present invention. Fig. 3A is an image taken in the absence of carbon dioxide 5 and storage unit 6. On the other hand, Fig. 3B is an image taken in the presence of carbon dioxide 5 and storage unit 6.
[0040] As shown in Figure 3A, the reflected light was magenta, whereas in Figure 3B, the reflected light was white instead of magenta.
[0041] In these experimental results, the use of the imaging unit 3 is important because no changes could be confirmed visually.
[0042] [Experimental environment 2] <Start> March 1, 2025, 14:09, temperature 18.7℃, humidity 46% <End> March 1, 2025, 14:33, temperature 18.9℃, humidity 46% The equipment used was the same as that used in Experimental Environment 1.
[0043] The angle θ, which is the inclination of the light emitted from the light-emitting unit 2 and reflected by the irradiated object 4 when viewed from the horizontal direction, was set to 135°±20°, the same as in experimental environment 1. In other words, the angle between the angle of incidence and the angle of reflection from the light-emitting unit 2 was 25° or more and 65° or less.
[0044] Fig. 4A is a diagram showing the results of imaging using a camera function of a smartphone, corresponding to at least one embodiment of the present invention. Fig. 4B is a diagram showing the results of imaging using a digital camera, corresponding to at least one embodiment of the present invention. Figs. 4A and 4B are images taken in the absence of carbon dioxide 5 and the presence of storage unit 6.
[0045] As shown in FIG. 4A, the reflected light was magenta. Also, as shown in FIG. 4B, the reflected light was also magenta. As such, regardless of which imaging means (imaging unit 3) was used, in the absence of carbon dioxide, the color of the reflected light remained unchanged and remained magenta. Furthermore, although not shown, visual observation showed no change from the magenta color leaning toward orange.
[0046] The inventors speculated that an increase in carbon dioxide concentration affects the reflected light from the lenses of glasses (wavelengths of electromagnetic waves in the visible light range), causing light to mix, and when photographed with a camera, magenta appears white.
[0047] Furthermore, the reason for the difference in color change between the naked eye and the camera is that the human eye does not perceive color as strongly in weak light, so in this case, a weak green light was generated, mixed with the magenta light, and captured as white light on camera. Furthermore, because the light was weak green when viewed with the naked eye, there was no change from the magenta light, which is closer to orange. We speculate that these are influenced by the rise in carbon dioxide concentration.
[0048] As one aspect of this embodiment, by adding the magnetic field and atmosphere of a celestial body to the method of inferring the presence or absence of an aurora, it becomes possible to increase the number of methods for inferring the celestial body environment.
[0049] As an aspect of this embodiment, it is possible to provide a device that allows new characteristics of light rays to be visually recognized.
[0050] [Second embodiment] The second embodiment is a variant of the first embodiment, and adopts the basic structure described in the first embodiment.
[0051] For example, the system 1 can be constructed as a system for checking the concentration of carbon dioxide. Currently, a sensor for checking carbon dioxide is used that uses the principle that carbon dioxide absorbs infrared rays. However, according to this embodiment, it is only necessary to sense the change in color of reflected light, and all that is required is a light-emitting unit that serves as a light source, an irradiated object, and an imaging unit that can take photographs. This makes it possible to construct a carbon dioxide checking system at lower cost than conventional systems, and is therefore useful. [Industrial Applicability]
[0052] The embodiments of the present invention are useful as educational experimental equipment that allows new characteristics of light rays to be visually recognized. [Explanation of symbols]
