The floating imaging module may further comprise an optical waveguide plate 1 and an image-out member capable of emitting light for imaging, the image-out member being disposed at one side of the optical waveguide plate 1 such that the light emitted by the image-out member can pass through the optical waveguide plate 1 to form an aerial image 2 at the other side of the optical waveguide plate 1. The sensing module is in signal connection with the control module and is used for detecting interaction actions of a user in a sensing area corresponding to the aerial imaging 2 and outputting interaction sensing information reflecting the interaction actions to the control module. The control module is used for realizing control related to the aerial imaging 2 according to the interaction induction information output by the induction module.

In particular, the optical waveguide plate 1 may comprise a matrix optical waveguide plate. The optical waveguide plate 1 may be mounted on an optical waveguide plate holder 3.

The interaction action can be an interaction action of a user, such as a gesture, or an action of the user holding other objects, such as a pen, and dividing in a sensing area.

The control related to the aerial imaging 2 may be control of the content of the aerial imaging 2, or may be control of audio playing related to the aerial imaging 2. For example, when the image output part is a display screen, the control of the content of the aerial image 2 may be to control the display screen to switch the displayed image. For another example, when a plurality of images corresponding to the same card 5 are stored in the internal memory of the control module, the control of the content of the aerial image 2 may be performed by switching the images. For example, the control of the audio playback may be playback control of starting, pausing, switching, etc. the audio corresponding to the aerial image 2.

In some embodiments, the floating imaging device may further include a filter element, where the filter element may be a component that screens incident light based on properties such as propagation direction, and selectively transmits some of the light. In some embodiments of the present disclosure, the filter element is configured to filter the outgoing light of the image output component, and screen the outgoing light within a preset angle range. The emergent light within the preset angle range can be emergent light perpendicular to the plane where the light-transmitting card, the display screen and the like in the image-outputting component are located. In some embodiments, the filter element may be a filter, and the filter element may be located between the image output component and the optical waveguide plate 1, where the light output surface of the filter element is disposed at an angle within an interval of (0, 90 °) with the light input surface of the optical waveguide plate 1 or the two surfaces are oblique, and the filter element is used to filter the light output from the image output component, screen the light output from the image output component within a preset angle range, and make the screened light output from the preset angle range enter the optical waveguide plate 1 to obtain aerial imaging.

In some embodiments, the filter as the filter element may be a polarized lens, which can effectively eliminate the interference of stray light in a specific direction, so as to obtain a clear image. In some embodiments, the optical filter as the optical filter element may further include a transparent substrate, on which an optical filter film is disposed, and on which a plurality of tiny gratings are disposed, which can pass incident light perpendicular to a plane in which the optical filter (or the optical filter film) is disposed, and block light in the remaining directions. As an example, the filter film may be a privacy film implemented based on the "ultra-fine shutter optical technique". In some embodiments, the plane of the optical filter as the optical filter element may be parallel to the plane of the light-transmitting card or the display screen in the image-outputting part. In still other embodiments, the filter element may be a filter film, such as a privacy film, in which case the filter film may be attached to a light-transmitting card in the imaging assembly or to the light-emitting surface of the display screen.

In some embodiments, the image-out member may further comprise a first light source 4 and a carrying structure 25 for carrying the card 5, and the card 5 may be a light-transmissive card. In some embodiments, the light transmissive card may be a card that is at least partially light transmissive. As an example, the light-transmitting card may include a light-transmitting area and a light-impermeable area, and the light-transmitting area and the light-impermeable area on the light-transmitting card may be combined together to form a certain hollowed-out pattern, and when light passes through the light-transmitting card, a projection image consistent with the hollowed-out pattern may be formed. For another example, the light-transmitting card may include two or more light-transmitting areas having different light transmittance or color, and the light-transmitting areas having different light transmittance or different color on the light-transmitting card may be combined together to form a certain pattern, and when light passes through the light-transmitting card, a projection image consistent with the pattern may be formed. In some embodiments, the carrying structure 25 can be such that the light-transmissive card carried by it is at least partially in the light path of the first light source 4. As an example, the carrying structure 25 may have an opening, and the light emitted by the first light source 4 is able to pass through the light-transmissive card after the light-transmissive card is placed onto the carrying structure 25 from the opening. The optical waveguide plate 1 is located above the supporting structure 25, when the supporting structure 25 supports the light-transmitting card, the optical waveguide plate 1 can be located on the light path of the emergent light of the light-transmitting card supported by the supporting structure 25, and the supporting structure 25 can enable the light-transmitting card supported by the supporting structure to be arranged at an imaging angle with the optical waveguide plate 1, so that the light transmitted through the light-transmitting card is physically refracted and reflected on the optical waveguide plate 1, and holographic floating imaging on the image side of the optical waveguide plate 1 is formed. The imaging angle may be a value between numerical intervals (0, 90 °). When the imaging angle is 0, the light entering the optical waveguide plate 1 from the image-outputting component is perpendicular to the optical waveguide plate 1, and at this time, the optical waveguide plate only acts as a light-transmitting medium, and does not play any role in reflection, so that the effect of aerial imaging 2 cannot be realized. When the light-transmitting card and the optical waveguide plate 1 are inclined (i.e., crossed), the outgoing light of the optical waveguide plate 1 is refracted in the air to form a floating image.

In some embodiments, the first light source 4 may be a surface light source or a point light source, and the first light source 4 may be fixed at the lamp panel bracket 24. As an example, the first light source 4 may be a light panel, specifically, the light panel may include a circuit board and a plurality of LED light beads disposed on the circuit board, the LED light beads are powered by a circuit on the circuit board, and the plurality of LED light beads may be arranged in a rectangular array to form a surface light source or an approximate surface light source. As another example, the first light source 4 may be a point light source such as a bulb, a single LED bead, etc., wherein the bulb may further be a combination of one or more of an incandescent lamp, a halogen lamp, an energy saving lamp, a solar lamp, etc.

In some embodiments, when the light transmissive card is carried by the carrying structure 25, the light transmissive card and aerial image 2 are symmetrical about the optical waveguide plate 1.

In some embodiments, the image output module may further include a light homogenizing structure, where the light homogenizing structure may be disposed between the first light source 4 and the supporting structure 25, and when the supporting structure 25 supports the light-transmitting card, the light-emitting surface of the light homogenizing structure is not perpendicular to the light-transmitting card supported by the supporting structure 25, and specifically, the light-emitting surface of the light homogenizing structure and the plane where the light-transmitting card supported by the supporting structure 25 is located may be parallel, or the two surfaces intersect but form an acute angle (i.e. oblique intersection). The light homogenizing structure is used for homogenizing incident light and emitting the homogenized light to the light-transmitting card supported by the supporting structure 25. As an example, the light homogenizing structure may comprise a light homogenizing sheet.

In some embodiments, the brightness of the first light source 4 ranges from 500 to 600 nit (nit, i.e., the unit of brightness, which refers to the physical quantity of intensity of the surface luminescence (reflection) of the illuminant (reflector). Some embodiments of the present disclosure can improve the defect that the light entering the optical waveguide plate 1 from the image output part is reduced due to the filter element, and further the brightness of the aerial image 2 is reduced, so as to provide a comfortable visual experience for the user by limiting the brightness value of the first light source 4 in the above range.

In some embodiments, the sensing module may include an infrared sensor 8, the infrared sensor 8 for sensing infrared radiation within the sensing region to generate interaction sensing information, the infrared sensor 8 in signal communication with the control module to transmit the interaction sensing information to the control module.

The infrared sensor 8 works on the principle that the heat effect of infrared radiation is utilized, the temperature rise is caused after the sensitive element of the detector in the infrared sensor 8 absorbs radiation energy, and then certain related physical parameters are changed, and the infrared radiation absorbed by the detector is determined by measuring the change of the physical parameters. In some embodiments, the infrared sensor 8 may detect infrared radiation generated by a user interacting through a body part within the sensing area, such as by the user pressing on aerial images within the sensing area using a palm, or by trying to click on aerial images with a finger. In still other embodiments, the infrared sensor 8 may also detect infrared radiation generated by a user interacting with an object within the sensing area, such as a user holding a pen, ruler, wand, or the like to click on an aerial image within the sensing area. The infrared sensor 8 may have a sensing range in which the output signal of the infrared sensor 8 changes when the infrared radiation fluctuates. Thus, some embodiments of the present description may obtain user interaction within the sensing area through the infrared sensor 8.

In order to cover the sensing area of the infrared sensor 8 with the aerial image 2 while avoiding unnecessary misrecognitions, the sensing area (light zone) of the infrared sensor 8 can be reduced to an accurate position by adjusting the power and angle of the infrared sensor 8. Specifically, the coverage area of the infrared sensor 8 can be changed by adjusting the power, and the coverage area of the infrared sensor 8 can be changed by adjusting the angle.

As an example, as shown in fig. 3, the infrared sensor 8 is located below the optical waveguide plate 1, the carrying structure 25 has an opening for inserting and extracting a card, the infrared sensor 8 is located above the opening, and the sensing range of the infrared sensor 8 covers the sensing area corresponding to the aerial image 2.

In an embodiment the sensing module may further comprise shielding structures 9 for blocking infrared radiation outside the sensing area from entering the infrared sensor 8. That is, the coverage of the infrared sensor 8 can be further reduced by providing the shielding structure 9, so that the infrared sensor 8 can be prevented from recognizing the card by mistake when the user inserts the card into the opening for inserting and extracting the card and/or when the user operates the touch key 16, and thus the holographic imaging is interrupted or disturbed.

As shown in fig. 3, the shielding structure 9 may be located below the optical waveguide plate 1, above the opening, and the area outside the sensing area includes at least an area for inserting and extracting a card determined based on the opening.

In some embodiments, the floating imaging device may further include a housing 10, in which a cavity is formed inside the housing 10, at least the imaging component, the sensing module, and the control module are accommodated in the cavity, a light-transmitting opening is formed at a top of the housing 10, and the outgoing light of the optical waveguide plate 1 can be emitted from the light-transmitting opening to form the aerial image 2.

In some embodiments, the light transmission opening may be an opening, where the optical waveguide plate 1 may be mounted, and in other embodiments, the opening may be provided with an additional transparent protective cover, and the optical waveguide plate 1 may be located below the opening. The arrangement is beneficial to protecting the optical waveguide plate 1 and prolonging the service life of the optical waveguide plate.

In some embodiments, the floating imaging device may further include a lamp holder, and the lamp holder may further include a light homogenizing cover and a second light source 11, where light emitted by the second light source 11 can exit from the light homogenizing cover and be displayed as ambient light.
