All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The features of the invention "first", "second" and the like in the description and in the claims may be used for the explicit or implicit inclusion of one or more such features. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.
The aerial imaging element and aerial imaging device of the present invention are described below in conjunction with fig. 1-5.
As shown in fig. 1, in the related art, a dihedral corner reflector includes: the plurality of fifth optical waveguides 100 and the plurality of sixth optical waveguides 200, the plurality of fifth optical waveguides 100 and the plurality of sixth optical waveguides 200 are orthogonally arranged to form an optical waveguide array, in the prior art, the angle between the fifth optical waveguides 100 and the horizontal plane is 45 °, and the angle between the sixth optical waveguides 200 and the horizontal plane is also 45 °, and we refer to this arrangement of the optical waveguide array as a forward arrangement, i.e. the inclination angle between the optical waveguide array and the horizontal plane is 0 °. The light emitted by the display screen is incident on the first reflecting surface of the fifth optical waveguide 100 and then totally reflected, the reflected light is incident on the second reflecting surface of the sixth optical waveguide 200 and totally emitted again, and then a floating real image 1:1 with the original image is formed in the air. Specifically, as shown in fig. 1, when the incident angle of the light is 0 °, the light is totally reflected twice, the reflection angle is also 0 °, and when the viewing angle range of the human eye is-30 ° -30 °, the human eye can see the floating real image. When the incident angle of the light exceeds 45 °, the light emitted by the display screen is directly incident on the sixth optical waveguide 200 for total reflection, i.e. the light is totally reflected once, so that there is an oblique afterimage on each of the left and right sides of the real image. At this time, when the visual range of human eyes exceeds-30 ° -30 °, the floating real image is not seen. Based on this, the embodiment of the invention provides an aerial imaging element and an aerial imaging device, which are used for solving the problems.
As shown in fig. 2, in the embodiment of the present invention, the aerial imaging element includes a pair of imaging lens assemblies, the pair of imaging lens assemblies are spliced, each imaging lens assembly includes at least one first optical waveguide array 10, the first optical waveguide arrays 10 are disposed obliquely, and the inclination angles of each first optical waveguide array 10 are not equal.
Specifically, in this embodiment, each imaging lens assembly includes one first optical waveguide array 10 or a plurality of first optical waveguide arrays 10, when each imaging lens assembly includes only one first optical waveguide array 10, the two first optical waveguide arrays 10 are spliced, and the inclination angles of the two first optical waveguide arrays 10 are different, for example, the inclination angle of one first optical waveguide array 10 is 20 ° and the inclination angle of the other first optical waveguide array 10 is 45 °, so that when light with an incidence angle of about-60 ° -60 ° is incident on the two first optical waveguide arrays 10, total reflection occurs twice to generate an aerial image, and at this time, the human eye can see the aerial image outside the range of-30 ° -30 °. Further, the inequality described in the present embodiment also includes that one first optical waveguide array 10 of the two first optical waveguide arrays 10 is inclined at an angle of 30 ° and the other first optical waveguide array 10 is inclined at an angle of-30 °.
Further, in the above-described embodiment, by disposing the two first optical waveguide arrays 10 obliquely, although the visual range in which the human eye sees the floating real image is enlarged, the afterimage still exists on both sides of the floating real image. When each imaging lens assembly includes a plurality of first optical waveguide arrays 10, the inclination angles of each first optical waveguide array 10 are different, so that light rays with different incidence angles can be totally reflected twice, and further, a floating real image can be seen within a range of 0-180 degrees, and no afterimage can be generated.
According to the aerial imaging element provided by the embodiment of the invention, at least two first optical waveguide arrays are obliquely arranged, so that light rays entering the first optical waveguide arrays in the forward direction and the oblique direction are subjected to total reflection twice, a floating real image is formed in the air, the visual range of a human eye capable of seeing the floating real image is enlarged, the residual image can be thoroughly eliminated by arranging a plurality of first optical waveguide arrays in each imaging lens assembly, and meanwhile, the human eye can see the floating real image in the visual range of 0-180 degrees; meanwhile, the aerial imaging element provided by the embodiment of the invention has the advantages of simple processing of the first optical waveguide array and low manufacturing cost, and is suitable for popularization and application.
Further, in the embodiment of the present invention, the plurality of first optical waveguide arrays 10 of the pair of imaging lens assemblies are symmetrically arranged.

When each imaging lens assembly only comprises one first optical waveguide array 10, the two first optical waveguide arrays 10 are symmetrically arranged, and the two first optical waveguide arrays 10 are spliced into a whole; when each imaging lens assembly includes a plurality of first optical waveguide arrays 10, the plurality of first optical waveguide arrays 10 in each imaging lens assembly are sequentially spliced and are arranged in one-to-one symmetry with the plurality of first optical waveguide arrays 10 in the other imaging lens assembly.

Further, after a part of light with an incident angle greater than 45 ° enters the first optical waveguide array 10, total reflection will also occur twice, so as to form a floating real image in the air. Further, the visual range in which the human eye can see the floating image is related to the inclination angle of the first optical waveguide array 10, and the larger the inclination angle is, the larger the visual range in which the human eye can see the floating image is.
Further, in order to ensure that no afterimage is generated, the number of the first optical waveguide arrays 10 in each imaging lens assembly can be set to be multiple, the multiple first optical waveguide arrays 10 are spliced in sequence, and the inclination angles of two adjacent first optical waveguide arrays 10 are different, so that light rays with any angle can be totally reflected twice after being injected into the imaging lens assembly, the afterimage can not be generated, and the visual range of the floating real image seen by human eyes can be enlarged.
Further, in this embodiment, the plurality of optical waveguides in the first optical waveguide array 10 are all stripe-shaped optical waveguides, the plurality of stripe-shaped optical waveguides are orthogonally arranged, and when the two first optical waveguide arrays 10 are spliced, only the optical waveguides in the two first optical waveguide arrays 10 need to be arranged obliquely relative to the forward direction in the prior art. In this embodiment, the first optical waveguide array 10 is simple to process and convenient to splice, and reduces the processing difficulty and manufacturing cost of the aerial imaging element.
Further, in another embodiment of the present invention, the number of the first optical waveguide arrays 10 in each imaging lens assembly is plural, and the plural first optical waveguide arrays 10 are spliced in turn, and the subsequent first optical waveguide array 10 is disposed obliquely with respect to the previous first optical waveguide array 10.
Specifically, when the number of the first optical waveguide arrays 10 in each imaging lens assembly is plural, the plural first optical waveguide arrays 10 are sequentially spliced, and the inclination angles of two adjacent first optical waveguide arrays 10 are different, so that the light rays with the incidence angles of 0 ° -90 ° or-90 ° -0 ° can be subjected to total reflection twice, thereby forming a floating real image without generating an afterimage.
Further, assuming that the number of the first optical waveguide arrays 10 in each imaging lens assembly is two, it is assumed that the light with the incident angle greater than 60 ° is totally reflected only once after being incident into the first optical waveguide array 10, and in this embodiment, by splicing one first optical waveguide array 10 after the first optical waveguide array 10, the light with the incident angle greater than 60 ° is incident into the second first optical waveguide array 10, and the inclination angle of the second first optical waveguide array 10 is different from that of the first optical waveguide array 10, the light with the incident angle greater than 60 ° is totally reflected twice in the second first optical waveguide array 10, so as to form a floating real image without generating an afterimage.

Light with an incidence angle larger than 45 degrees is incident into the first optical waveguide array 10 and then totally reflected twice, so that a floating real image is formed and no afterimage is generated.

Further, when light is obliquely incident into the first optical waveguide array 10, since the included angle between the first optical waveguide 11 and the horizontal plane is smaller, the obliquely incident light can be just incident into the first optical waveguide 11 and reflected by the first optical waveguide 11 to the reflecting surface of the second optical waveguide 12, and a floating real image is formed in the air after the second optical waveguide 12 is reflected, so that an afterimage is not generated.
