[0030] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0031] See also Figure 1 , the present embodiment provides a mobile phone microscopic imaging module, comprising: a glass substrate 1, an optical core panel 3 and a chip 4; the optical core panel 3 is arranged at the lower surface of the glass substrate 1, the chip 4 is arranged at the bottom surface of the optical core panel 3, and a filter structure (not shown in the figure) is arranged between the optical core panel 3 and the chip 4; in the present application, when performing microscopic imaging, a glass sheet 5 with cell slices is placed on the upper surface of the glass substrate 1, and then the optical core panel 3 projects the cell image of the glass substrate 1 onto the filter structure to filter stray light and then projects it onto the chip 4 for computational imaging; wherein, the optical core panel 3 can project the image of a tiny object onto the chip 4, and calculate the imaging through the chip 4, so as to achieve the purpose of microscopic imaging, and at the same time, the microscopic imaging module in the present application has an optimized structure and a small size, and a filter structure is arranged at the bottom surface of the optical core panel 3 instead of the filter in the prior art, which can further reduce the overall structural size of the microscopic imaging module, realize a miniaturized design, and after being assembled to the mobile phone, the miniaturized design of the mobile phone is correspondingly realized.
[0032] Furthermore, the filter structure is configured as an infrared cut-off film.
[0033] For further information, see Figure 1 The optical core panel 3 has a plurality of micron-scale optical waveguides 31, which are regularly arranged inside the optical core panel 3. Specifically, the optical waveguides 31 are vertically and spaced apart inside the optical core panel 3, and adjacent optical waveguides 31 have excellent optical insulation properties, which can enable the optical image to penetrate a transparent layer of more than 3 mm without deteriorating the image quality, that is, the optical waveguide 31 can stably project the cell image on the glass substrate 1 onto the chip 4, and can effectively block the ambient stray light from entering the chip 4, thereby ensuring the accuracy of image signal extraction, and further ensuring the image accuracy of microscopic imaging.
[0034] It is worth mentioning that an optical waveguide is a dielectric device that guides light waves to propagate in it, also known as a dielectric optical waveguide. There are two major categories of optical waveguides: one is an integrated optical waveguide, including planar (thin film) dielectric optical waveguides and strip dielectric optical waveguides, which are usually part of optoelectronic integrated devices (or systems), so they are called integrated optical waveguides; the other is a cylindrical optical waveguide, usually called an optical fiber (see optical fiber).
[0035] In this example, see Figure 1 - Figure 3 The optical waveguide 31 includes an optical fiber 32 and a fiber cladding 33, wherein the fiber cladding 33 has optical fibers 32 arranged in a predetermined manner; specifically, the optical core panel 3 is actually composed of tens of millions of optical fibers 32 with a diameter of 4 pm to 6 pm, which are fused in a regular arrangement, wherein each optical fiber 32 can transmit an image at a corresponding position to the chip 4 (see Figure 3 ), that is, the optical fiber 32 can realize point-to-point transmission of the image. Therefore, the present application can stably project the image of the tiny cells on the glass substrate 1 onto the chip 4 through the optical fiber 32, thereby realizing the microscopic imaging effect.
[0036] It is worth noting that the optical fibers in the present application are arranged vertically and at intervals. When the arrangement of the optical fibers is changed, the output mode of the image can be changed. Specifically, when the optical fibers 32 in the optical core panel 3 are arranged horizontally and at intervals, and the intervals between every two adjacent optical fibers 32 are the same, zero-thickness image transfer is achieved (see Figure 4 ); When the optical fiber 32 in the optical core panel 3 is arranged horizontally at both ends and the two horizontal sections are twisted to form a twist zone, short-distance image inversion can be achieved (see Figure 5 ); when the optical fiber 32 in the optical core panel 3 is arranged from the side of the image intake to the side of the image output, the image zoom can be achieved (see Figure 6); therefore, the arrangement of the optical fibers can be changed according to actual needs to achieve corresponding image effects.
[0037] Furthermore, a filter structure is plated on the bottom surface of the optical core panel 3, wherein the substrate of the optical core panel 3 is suitable for coating, and the filter structure is used to replace the filter in the prior art, which can further reduce space and cost and achieve the purpose of microscopic imaging.
[0038] For further information, see Figure 1 , LED lamp beads 2 are arranged at the edge of the glass substrate 1, and the LED lamp beads 2 are used to provide light, so that the optical core panel 3 can more clearly obtain the cell image on the glass substrate 1. At the same time, in this embodiment, in order to improve the lighting effect, multiple LED lamp beads 2 are evenly arranged on the glass substrate 1 around its center line. The multiple LED lamp beads 2 provide light at the same time, which can further improve the image clarity on the glass substrate 1.
[0039] Furthermore, a circuit board (not shown in the figure) is provided at the bottom surface of the chip 4, and the chip 4 is electrically connected to the circuit board. At the same time, a connector is provided on one side of the circuit board, and the connector is used to connect to an external power supply, so as to provide power or signal transmission for each electronic component in the imaging module through the circuit board.
[0040] Compared with the prior art: the mobile phone microscopic imaging module of the present application comprises: a glass substrate 1, an optical core panel 3 and a chip 4; the optical core panel 3 is arranged at the lower surface of the glass substrate 1, the chip 4 is arranged at the bottom surface of the optical core panel 3, and a filter structure is arranged between the optical core panel 3 and the chip 4; in the present application, when performing microscopic imaging, a glass sheet 5 with cell slices is placed on the upper surface of the glass substrate 1, and then the optical core panel 3 projects the cell image of the glass substrate 1 onto the filter structure to filter stray light and then projects it onto the chip 4 for computational imaging; wherein, the optical core panel 3 can project the image of a tiny object onto the chip 4, and calculate the imaging through the chip 4, so as to achieve the purpose of microscopic imaging. At the same time, the microscopic imaging module in the present application has an optimized structure and a small size, and a filter structure is arranged at the bottom surface of the optical core panel 3 instead of the filter of the prior art, which can further reduce the overall structural size of the microscopic imaging module and realize a miniaturized design, and after being assembled to the mobile phone, the miniaturized design of the mobile phone is correspondingly realized.
