The cylindrical housing 2 is a core component of the optical path display device provided in this embodiment, and has a folding/reflecting plane and a see-through plane, wherein the folding/reflecting plane is disposed in a length direction and is opposite to the see-through plane, the folding/reflecting plane is disposed opposite to the see-through plane, and can ensure total reflection of light, and the folding/reflecting plane is disposed transparent to ensure that light can pass through and refract. The perspective plane between the oppositely arranged folding/reflecting planes can be in the shape of a cambered surface or a plane, and the like, and the embodiment preferably adopts a plane, because the perspective plane is the plane, the display is the clearest and the distortion is the least.

It can be seen that the cross section of the cylindrical shell 2 in the length direction may be any shape while ensuring a pair of folding/reflecting planes arranged oppositely and a perspective plane between the folding/reflecting planes arranged oppositely. Considering the reasons in the aspect of cost, display definition, distortion factor, the preferred cuboid shape that adopts of column casing 2 in this embodiment can adopt glass material or organic glass material or plastics material, and the preferred organic glass material that adopts of this embodiment. One set of opposite surfaces of the rectangular parallelepiped cylindrical case 2 can form a folding/reflecting plane which is arranged oppositely, and one surface of the other set of opposite surfaces can form a perspective surface.

The rectangular parallelepiped cylindrical housing 2 is mounted to the holder 1 through the first and second fixing covers 11 and 12, and therefore, the shapes of the first and second fixing covers 11 and 12 must also match the shape of the cross section of the cylindrical housing 2. In this embodiment, in order to display more completely, the first fixing sleeve 11 and the second fixing sleeve 12 are both transparent.

The connecting piece 13 and the positioning groove 14 can be in transition fit or interference fit, and the cylindrical shell 2 is kept static by the friction force between the connecting piece 13 and the groove wall of the positioning groove 14. The first fixing sleeve 11 and the second fixing sleeve 12 can slide in the same direction in the positioning slot 14 to rotate the rectangular parallelepiped cylindrical housing 2. After rotating to a proper angle, the cylindrical shell 2 is kept still at a certain angle after rotating by the friction force between the connecting piece 13 and the groove wall of the positioning groove 14.

The columnar shell 2 is filled with a light-transmitting liquid, and the light-transmitting liquid is one of a copper sulfate solution, a sodium hydroxide solution, a dilute sulfuric acid solution, a dilute hydrochloric acid solution, water and milk, and water is preferably used in the embodiment.

Meanwhile, the columnar shell 2 is provided with a liquid inlet and outlet hole for the light-transmitting liquid to flow in/out so as to replace the light-transmitting liquid, and the liquid inlet and outlet hole is provided with a sealing plug or a sealing cover so as to prevent the light-transmitting liquid from flowing out.

When the point light source 3 is incident into the cylindrical housing 2 from one end of the cylindrical housing 2 or the outside of the folding/reflecting plane and passes through the water for light transmission, the light path of the light emitted by the point light source 3 passing through the water in the cylindrical housing 2 can be observed from the light transmission surface.

In this embodiment, since the scale 15 is white, in order to make the light path display more obvious and clear, black background paper is attached to one surface of the rectangular parallelepiped cylindrical housing 2 close to the scale 15, i.e., the opposite surface of the perspective surface, and the light path display is more obvious and clear since the color difference between the black background paper and the white scale 15 is strong.

As shown in fig. 1, a thick line in the figure is a light path which is presented by the light path display device when light propagates along a straight line, the cylindrical shell 2 in a cuboid shape is horizontally static, the point light source 3 emits light from one end of the cylindrical shell 2, and the angle of the point light source 3 is adjusted to ensure that the light does not strike on the folding/reflecting plane on the upper side or the lower side, so that the light passes through water in the cylindrical shell 2 to be emitted, and then the light path when the light propagates along the straight line is presented.

As shown in fig. 2, the thick line in the figure is the light path that appears through the light path display device when the refraction phenomenon occurs to the light, the cylindrical shell 2 of cuboid shape is horizontal static, the point light source 3 jets out the light from the upside or the downside of the cylindrical shell 2, the light passes through the transparent refraction/reflection plane, jets into the water in the cylindrical shell 2, because the cylindrical shell 2 is filled with water, the refraction phenomenon can occur because the refraction index of water is different from the refraction index of air, and then the light path when the refraction phenomenon occurs to the light is presented. Since the scale 15 is attached to the background plate, the refractive index can be calculated from the angle of the optical path.

As shown in fig. 3, a thick line in the figure is a light path which is presented by the light path display device when the light is totally reflected, the rectangular prism-shaped cylindrical shell 2 is horizontally static, the point light source 3 emits light from one end of the cylindrical shell 2, the angle of the point light source 3 is adjusted to make the light strike on the folding/reflecting plane at the upper side or the lower side, and then the total reflection occurs, and once the light strikes on the folding/reflecting plane at the upper side or the lower side, the total reflection occurs until the light passes through the water in the cylindrical shell 2 to be emitted, and then the light path when the light is totally reflected is presented.

As shown in fig. 4, the thick line in the figure is the light path that the light path display device presents when the light refracts, and fig. 4 is relative to fig. 2, the rectangular parallelepiped cylindrical housing 2 is rotated to change the angle, so the principle of the light path display is the same as fig. 2, except that fig. 2 is rotated to form fig. 4, so as to simulate the situation when the interface between different media is angularly deflected. In general, when calculating the refractive index, the interface between different media is set to 0 °, and the reading of the optical path angle and the calculation of the refractive index of the media are performed based on this. When the interface between different media deflects, it is usually hard to detect the deflection due to the error collision or the small deflection angle, so the angle of the interface between different media is still calculated as 0 °, and in this case, the calculated refractive index will generate an error. Fig. 4 is a simulation of this in order to calculate and analyze the error in the refractive index calculated when the interface between the different media is deflected.

While the present invention has been described with reference to the particular illustrative embodiments, it will be understood by those skilled in the art that the present invention is not limited thereto, and may be embodied in many different forms without departing from the spirit and scope of the present invention as set forth in the following claims.
