Description

Technical Field

[0001] The utility model relates to the technical field of image transmission, in particular to a system for transmitting temperature field images by using a disordered fiber optic bundle. Background Art

[0002] Disordered fiber optic bundles are generally used in occasions where only light energy needs to be transmitted, such as fiber optics for flame detection, fiber optic bundles for lasers, etc. Such a fiber optic bundle is usually composed of tens of thousands of independent optical fibers arranged disorderly, and the arrangement order of the optical fibers at the entrance end is inconsistent with that at the exit end, and only light energy signals can be transmitted between the entrance and the exit. Taking a 5x5 array of disordered fiber optic bundles as an example, if the position coordinates corresponding to the optical fibers on the light incident surface are marked, with the abscissa serial numbers 1-5 and the ordinate serial numbers 1-5, the positions on the light incident surface of the optical fibers are a regular sequence from 11-55 (the first number represents the abscissa position and the second number represents the ordinate position). However, at the light exit surface of the optical fibers, due to no strict sorting, the position sequence of the corresponding optical fibers is in a disordered state. Such a disordered state is a unique state for each independent fiber optic bundle.

[0003] Ordered fiber optic bundles are also called image transmission bundles. Since the arrangement order of the optical fibers at the entrance end is exactly the same as that at the exit end, they can be used not only for energy transmission but also for image transmission. Such as image transmission bundles used in medicine, image optical fibers for industrial endoscopes, and fiber optic array bundles for aerospace, etc.

[0004] The manufacturing processes of fiber optic bundles mainly include:

[0005] 1. Stacking method: Multiple optical fibers are arranged side by side and fixed into a bundle with glue or heat-melt sleeves. This method has a simple process, but the regularity of the bundle cross-section is poor.

[0006] 2. Drawing method: A prefabricated optical fiber rod or optical fiber strip is heated and stretched to make a slender fiber optic bundle. This method can prepare fiber optic bundles with high density and high regularity, but the process is complex and the cost is high.

[0007] There is a huge difference in the cost between disordered fiber optic bundles and ordered fiber optic bundles. Due to the high price of ordered fiber optic bundles, their application scope is greatly limited.

[0008] Patent document CN209514126U discloses a multi-spectral channel image transmission fiber optic bundle system, which includes an image transmission module and a multi-spectral channel imaging module. The image transmission module is an image transmission fiber optic bundle, which includes an image acquisition end and an image output end; the image acquisition end is a common end, connected to two lenses, respectively connected to two fiber optic bundles; the two fiber optic bundles output optical signals through two-stage output ports at the image output end. For each output port, an objective lens, a filter, and a dichroic mirror are arranged in sequence along the optical path. After the objective lens of each path collimates the optical signal of its corresponding output port, it is transmitted to its corresponding filter for band-pass filtering, and then reflected by the corresponding dichroic mirror for the optical signal of this channel; among them, the dichroic mirror corresponding to the second output port reflects the optical signal of the second output port, and at the same time transmits the optical signal reflected by the dichroic mirror of the first output port, and transmits it to the multi-spectral channel imaging module to obtain the synchronous imaging results of multi-spectral and multi-visual fields.

[0009] In the above solution, the solution uses an orderly arranged fiber optic bundle for image transmission. However, the cost of the orderly arranged fiber optic bundle is relatively expensive. Therefore, it is necessary to provide a system that uses a disorderly arranged fiber optic bundle for temperature field image transmission to solve the deficiencies of the existing technology.

[0036] To make the objectives, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the utility model. The components of the embodiments of the utility model described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model to be protected, but merely represents selected embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0037] Embodiment 1:

[0038] In this embodiment, as Figure 1-2As shown in the figure, a system for temperature field image transmission using a disordered arrangement of optical fiber bundles proposed by the present utility model includes an image input unit 1, a first image scaling unit 2, an image transmission unit 3, a second image scaling unit 4, an image output unit 5, and a computer terminal 6. The image input unit can output signals; the image scaling unit can receive and preliminarily scale the signals output by the image input unit; the image transmission unit can receive and transmit the signals output by the first image scaling unit. The number of signals at the input end and the output end of the image transmission unit is the same, but the arrangement order is inconsistent; the second image scaling unit can receive and further scale the signals output by the image transmission unit; the image output unit can display the signals output by the second image scaling unit; the computer terminal is respectively connected to the image input unit and the image output unit. The image input unit outputs signals under the control of the computer terminal, and the image output unit displays the output signals on the computer terminal. The computer terminal stores the correspondence between the signals at the input end and the output end of the image transmission unit.

[0039] In this embodiment, it is further set that the image input unit includes an LED light source array. The LED light source array is arranged with individual pixels, and the individual pixels can be controlled by the computer terminal and independently lit in turn to emit signals.

[0040] In this embodiment, it is further set that the first image scaling unit includes an objective lens group. The objective lens group can preliminarily scale the individual pixels of the LED light source array to meet the requirements of the input end of the image transmission unit. The objective lens group is a lens system composed of several lenses combined in a certain arrangement. These lenses are usually glued together by one or several lenses of different materials and different parameters, and are separated from each other by a certain distance to reduce aberration. Each group of lenses undertakes specific optical tasks, such as correcting chromatic aberration, spherical aberration, coma aberration, etc., to improve the imaging quality.

[0041] In this embodiment, it is further set that the image transmission unit includes an optical fiber bundle light incident surface 301, an optical fiber bundle 302, and an optical fiber bundle light exit surface 303. The optical fiber bundle light incident surface can image the individual pixels scaled by the objective lens group; the optical fiber bundle is composed of several optical fiber filaments, and the optical fiber filaments are arranged disorderly. The optical fiber bundle light exit surface corresponds one by one to the individual pixels imaged by the optical fiber bundle light incident surface; the optical fiber bundle light exit surface can output the signals transmitted by the optical fiber filaments, and the output signals of the optical fiber bundle light exit surface are inconsistent with the input signals of the optical fiber bundle light incident surface in terms of arrangement order.

[0042] In this embodiment, it is further set that the second image scaling unit includes an eyepiece lens group, which can further scale the signal output by the image transmission unit to meet the requirements of the image output unit. The eyepiece lens group usually consists of two groups of lenses. One group of lenses is the ocular lens (also known as the eyepiece or the forward-bending negative meniscus lens), which plays a major magnifying role; the other group of lenses is the converging lens or the field lens, whose function is to make the image brightness uniform and ensure the image clarity.

[0043] In this embodiment, it is further set that the image output unit includes an image sensor, which can display the signal scaled by the second image scaling unit as an image. The image sensor is an important optoelectronic conversion device that can convert optical signals into electrical signals and then generate digital images. This technology is prior art.

[0044] In this embodiment, it is further set that the image transmission unit further includes a constraint component 304, which can fix the position of each optical fiber filament to prevent the change of the correspondence between the input signal and the output signal of the image transmission unit caused by the movement of the optical fiber filaments, resulting in system data errors, incomplete or incorrect imaging display.

[0045] Embodiment 2:

[0046] In this embodiment, as Figure 1-3 shown, Figure 3 is an optical fiber bundle arranged in an orderly manner in the prior art. This optical fiber bundle is also called an image transmission bundle, and the arrangement order of the optical fibers at the entrance end is exactly the same as that at the exit end. The difference from Embodiment 1 is only whether the arrangement order of the entrance end and the exit end of the optical fiber bundle is the same, but the cost difference is large, resulting in limited application scope of the orderly arranged optical fiber bundle.

[0047] The working principle of the system for temperature field image transmission using a disorderly arranged optical fiber bundle is as follows: An instruction is issued by the computer terminal to independently light the individual pixels of the LED light source array in turn. The individual pixel LED light source at the (x, y) position on the LED light source array can be accurately imaged at the (x, y) position on the light incident surface of the optical fiber bundle of the image transmission unit after being scaled by the objective lens group. The light exit surface of the optical fiber bundle corresponds one by one to the individual pixel imaged on the light incident surface of the optical fiber bundle. Therefore, the computer terminal can light the individual pixels at known positions of the LED light source array, and the signal is transmitted through the corresponding optical fiber filaments to the (i, j) position on the light exit surface of the other end of the disorderly arranged optical fiber bundle. Finally, the signal on the light exit surface of the optical fiber bundle is imaged at the (i, j) position on the image sensor through the eyepiece lens group. Through the automatic recognition of the computer terminal, the position correspondence relationship of each optical fiber filament on the light incident surface of the optical fiber bundle to the light exit surface can be calculated and the position correspondence file can be stored and recorded.

[0048] When creating the position correspondence file, the computer terminal first generates an empty two-dimensional array A with m rows and n columns. Then, it alternately lights up the individual pixel light-emitting points on the LED light source array in a certain row and column order. The current lighting position coordinates are recorded as the array (x, y). Next, according to the position of the highlighted pixels on the image sensor, the arrangement position coordinates of the light-emitting surface of the optical fiber bundle corresponding to this light-emitting point are identified, and the corresponding position coordinates are (i, j). Finally, let the array Ai,j = (x, y) and save it until all pixels are recognized and recorded. The array A is the position correspondence file, and its structure is as follows:

[0049]

[0050] Using the position correspondence file: Assume that the position correspondence file has been generated, and its internal information is the value A. The image information currently collected by the image acquisition system is P (P is a two-dimensional array, and for simplicity of description, it is also m rows and n columns). First, read the information of the array A and traverse the elements in the A array. If the current element Ai,j = (x, y), shift the pixel information Pi,j on the image sensor to the position (x, y) until all pixels have been correctly placed and the image restoration is completed.

[0051] In the description of the present invention, it should be noted that when terms indicating the orientation or position relationship such as "upper", "lower", "inner", "outer", "left", "right" appear, they should be understood as based on the orientation or position relationship shown in the drawings, or the orientation or position relationship when the product of the present invention is normally placed, or the orientation or position relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present invention. In addition, when terms such as "first" and "second" appear, they are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should also be noted that unless otherwise clearly specified and limited, terms such as "installation", "setting", "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
