Description

Technical Field

[0001] The present invention relates to the field of optical systems, in particular to an electronic sight mark generating device for a synoptophore. Background Art

[0002] A synoptophore is a medical device used to diagnose and treat binocular vision disorders, such as strabismus, amblyopia, and fusional abnormalities. Its core technology, based on the principle of binocular dichoptic vision, uses an optical system to provide independent visual stimulation to each eye, simulating images from different perspectives to assess and train binocular coordination.

[0003] Synoptophores play a crucial role in ophthalmology, with their functionality and accuracy directly impacting the accurate diagnosis and effective treatment of eye diseases. This device, through its unique design, can separate the subject's binocular visual field, presenting different images to the left and right eyes, respectively. This provides doctors with an accurate basis for assessing the subject's binocular visual function. In the construction of a synoptophore, the optotype is a core component responsible for displaying the images used for testing. With the continuous advancement of ophthalmic diagnostic and treatment technology, higher requirements are being placed on the performance of optotypes. In traditional synoptophores, optotypes display images via slides, such as a lion cage image or a cross ring. The types of optotypes displayed are limited, and the displayed images are static, which limits the effectiveness of synoptophores in detecting and training binocular vision function.

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] This embodiment provides an electronic sight mark generating device for a synoptophore, comprising:

[0034] A first display module and a second display module are arranged side by side so that the left eye and right eye of the subject face the first display module and the second display module respectively. The first display module is used to display a first test image and emit light of the first test image to the left eye of the subject. The second display module is used to display a second test image and emit light of the second test image to the right eye of the subject.

[0035] The sight mark generation module is connected to the first display module and the second display module respectively, and is used to process images and generate image data, and transmit the image data to the first display module and the second display module respectively, so that the first display module displays the first test image and the second display module displays the second test image.

[0036] The sight mark generation module processes the image and generates image data, transmitting the image data to the first and second display modules. The first display module displays the first test image, directing light from the first test image to the subject's left eye. The second display module displays the second test image, directing light from the second test image to the subject's right eye.

[0037] In this embodiment, the electronic sight mark generating device for the synoptophore processes images and generates image data by means of a sight mark generating module, so that the first display module displays the first test image and the second display module displays the second test image. Compared with the existing method of displaying images through slides, it can display more diverse test images and more dynamic test images.

[0038] The electronic sight mark generating device for the synoptophore in this embodiment can display more diverse test images, make the test images more dynamic, and enable the synoptophore to achieve a more comprehensive and accurate assessment of the visual function of the subject. This is not only crucial for the early detection of ophthalmic diseases, but also plays an indispensable role in the diagnosis and treatment process.

[0039] In some embodiments, the first display module includes a first visual lens and a first display, the first display is used to display the first test image, so that the first test image light emitted by the first display passes through the first visual lens and then exits to the left eye of the subject; the second display module includes a second visual lens and a second display, the second display is used to display the second test image, so that the second test image light emitted by the second display passes through the second visual lens and then exits to the right eye of the subject. The first visual lens and the first display are correspondingly arranged, and the second visual lens and the second display are correspondingly arranged. The left eye of the subject faces the first visual lens, and the right eye of the subject faces the second visual lens. In this way, the subject's binocular vision is separated, and independent visual stimulation is provided to the left and right eyes of the subject. For example, reference can be made to Figure 1 , Figure 1This is a schematic diagram of an electronic sight mark generation device for a synoptophore, provided in accordance with one embodiment. As shown, a first visual lens 101 and a second visual lens 102 are arranged side by side. The first visual lens 101 is correspondingly arranged with a first display 103, and the second visual lens 102 is correspondingly arranged with a second display 104. A sight mark generation module 105 is connected to the first display 103 and the second display 104, respectively.

[0040] When configuring the first and second visual lenses 101 and 102, the following key considerations should be considered: 1) Field of view: Selecting a visual lens with a wider field of view allows the subject to observe a wider area, facilitating a more comprehensive binocular vision test and reducing blind spots. A monocular visual lens with a horizontal viewing angle of approximately 60° is suitable. 2) Refractive angle: The visual lens should have a refractive adjustment function to accommodate the individual's vision, ensuring a clear view of the image on the display and ensuring the accuracy of the inspection results. 3) Comfort: The visual lens should be ergonomically designed, with a soft material for the eye contact portion to minimize discomfort during the inspection and adapt to the individual's facial features and observation habits. 4) Optical quality: The visual lens should have excellent optical performance, with high clarity, low distortion, and minimal chromatic aberration to ensure the quality of the image observed by the subject and prevent optical factors from affecting the inspection results. Accordingly, in some embodiments, the horizontal viewing angle of the first visual lens 101 or the second visual lens 102 can reach 60±5°. In some embodiments, the diopter of the first visual lens 101 and the diopter of the second visual lens 102 are adjustable. The diopter adjustment range of the first visual lens 101 or the second visual lens 102 can be ±5D to ±10D, which can meet the needs of most testing situations and support diopter adjustment of 0 to 400D for myopia.

[0041] When configuring the first display 103 and the second display 104, the following key considerations should be considered: 1) Panel type: The selected panel should provide good contrast and color performance, which helps improve treatment and measurement effectiveness. 2) Resolution: A higher resolution makes the displayed image clearer and more detailed, which is crucial for accurately observing and diagnosing eye conditions. 3) Frame rate: A higher frame rate ensures image smoothness, reducing lag and stuttering when observing eye movements in real time. 4) Size: This should be determined based on the overall design and usage scenario of the electronic sight mark generation device. In some embodiments, the first display 103 or the second display 104 may utilize an organic light-emitting diode (OLED) panel. OLED panels utilize a multilayer organic thin film structure to generate electroluminescence. They utilize a very thin organic material coating and a glass substrate. When an electric current flows through them, the organic material emits light. OLED panels can be made lighter and thinner, offer wider viewing angles, and significantly reduce power consumption. For example, in a specific instance, a 3.5-inch OLED panel can be selected, with an active color matrix with a resolution of 1920×1080, integrated panel drive and logic drive, small size, light weight, low power consumption, and can be embedded in the body of the electronic visual mark generating device. Alternatively, a 0.9-inch Micro OLED panel can be selected, with a resolution of 2560×2560 and a refresh rate of 120Hz. Taking into account that the test image is to be presented to the subject for viewing, the resolution and refresh rate of the display become key indicators. A high-resolution display is selected to ensure the accurate presentation of image details. At the same time, a high refresh rate ensures the smoothness of dynamic image switching, avoiding the impact of image delay or ghosting on the test effect, and aims to provide the subject with a clear and stable visual experience.

[0042] In some embodiments, the first display 103 or the second display 104 is covered with a cover plate to prevent dust. The cover plate can be an optical glass cover plate. For example, the hardness of the optical glass cover plate is ≥8H, reaching IP54 level protection, which can effectively enhance the anti-interference performance.

[0043] In some embodiments, the first display module further includes a first drive circuit module connected to the first display 103 for controlling the image display on the first display 103. The second display module further includes a second drive circuit module connected to the second display 104 for controlling the image display on the second display 104. The visual lens, display, and drive circuit module are key components for displaying the processed test image.

[0044] In some embodiments, the sight mark generation module 105 is used to generate an editable first reference image and a second reference image, and to translate and / or rotate and / or scale the first reference image and the second reference image respectively to generate a first sight mark and a second sight mark that meet the requirements, and to generate a first visual scene and a second visual scene according to the requirements, to generate a first test image according to the first sight mark and the first visual scene, and to generate a second test image according to the second sight mark and the second visual scene.

[0045] Optotypes can be geometric shapes, letters, numbers, symbols, or images of natural scenes, providing a variety of test images to meet the needs of different eye examinations. Geometric shapes can be used to assess the subject's basic visual function, while letters, numbers, or symbols can help check the subject's reading ability and vision. Natural scene images can more realistically simulate daily living environments, thereby more accurately assessing the subject's visual adaptability. Geometric shapes can be crosses, circles, or random dot stereograms.

[0046] Generating a first test image based on a first optotype and a first visual scene, or generating a second test image based on a second optotype and a second visual scene, can consider performance indicators such as image switching speed, resolution, and display stability. This electronic optotype generating device generates test images based on optotypes and visual scenes, enabling the provision of richer and more varied test images, thereby achieving a more comprehensive and accurate assessment of the subject's visual function. This is not only crucial for the early detection of ophthalmic diseases, but also plays an indispensable role in the diagnosis and treatment process.

[0047] In some embodiments, the sight mark generation module 105 may include a processor for processing and generating images and performing logical calculations. The sight mark generation module 105 is the "brain" of the electronic sight mark generation device for the synoptometer, responsible for generating and processing various test images. The sight mark generation module 105 needs to have powerful computing power and efficient image processing capabilities. The processor can be a high-performance processor or a dedicated image processing chip to meet the needs of real-time generation and processing of high-quality images. In addition, the sight mark generation module 105 can also be equipped with sufficient memory and storage space to ensure stable system operation and fast data reading and writing. For example, in a specific embodiment, an FPGA Zynq-7000 series chip can be selected. It integrates an ARM Cortex-A9 dual-core processor with a maximum operating frequency of 866MHz, contains 512MB of DDR3 SDRAM, and has sufficient logic units for image processing acceleration and high-performance computing. It has rich I / O interface resources and is responsible for real-time image processing and synchronous control. In some embodiments, the visual mark generation module 105 can use the C++ high-level programming language in combination with image processing libraries such as OpenCV to achieve efficient image processing and display functions, while paying attention to aspects such as code standardization, readability, and performance optimization to ensure the quality and efficiency of the software.

[0048] In some embodiments, the electronic sight mark generation device for a synoptoscope further includes a control interface module 106 connected to the sight mark generation module 105 for coordinating and controlling the operation of the sight mark generation module 105, the first display module, and the second display module, as well as for connecting to external devices. The control interface module 106 is the hub of the entire device, responsible for coordinating and controlling the operation of each module to ensure that the entire device operates according to predetermined procedures and processes. The control interface module 106 can have stable performance and strong scalability to accommodate future functional upgrades and expansion requirements. In one specific example, the control interface module 106 can utilize TI's high-performance USB 3.0 physical layer chip, the TUSB1310A. This chip supports USB 3.0 Gen 1 (5 Gbps) and USB 2.0 (480 Mbps) communication protocols, offers low power consumption, a power-saving mode, and integrates a USB physical layer interface (PHY) and control logic, making it suitable for compact designs.

[0049] For example, you can refer to Figure 1 and Figure 2 , Figure 2 A schematic diagram of an electronic sight mark generating device for a synoptophore is provided as another embodiment. As shown in the figure, the control interface module 106 is connected to the sight mark generating module 105 and is used to connect to an external device, such as a computer or a laptop. Figure 2The processor shown uses a Field Programmable Gate Array (FPGA). The first display 103, the second display 104 and the FPGA can communicate in real time via a serial RS232 interface. Figure 3 , Figure 3 The present invention provides an electrical connection diagram of a control interface module of an electronic sight mark generating device for a synoptophore, provided in one embodiment. The control interface module 106 is connected to an FPGA and a computer, respectively. The JTAG port is used for internal chip testing and is a reserved port. The XI port, XO port, and VSSOSC port represent external reference clock ports, corresponding to clock signal input, clock signal output, and ground signal, respectively. The PIPERX port and PIPE TX port are universal parallel interfaces between the USB interface and the bus interface and the MAC layer controller. The bus can be a PCIe bus. PCIe is a high-performance bus standard that regulates data communication between various components within a computer. The bus interface is the physical layer interface (PHY), which is responsible for processing the lowest-level physical signals. The MAC layer is the media access control layer, which is a logical control circuit above the physical layer that ensures that data is sent and received correctly, orderly, and efficiently.

[0050] The control interface module 106 can be a pure USB 3.1 physical layer transceiver that does not process USB 2.0 signals. When USB 2.0 data signals are present, a separate USB 2.0 PHY chip is required, connected to the FPGA via the ULPI port. The ULPI port is used to facilitate data communication between the USB 2.0 PHY chip and the FPGA and is a reserved port. For example, the control interface module 106 uses the TUSB1310A. The SSRXP, SSRXN, SSTXP, and SSTXN ports are responsible for differential signal pairs for USB 3.1 and higher data transmission speeds. The SSRXP port is used for SuperSpeed ​​positive-polarity reception. This is the positive terminal of the SuperSpeed ​​differential pair received by the physical layer interface (PHY) chip and is connected to the corresponding RX pin of the USB connector. The SSRXN port is used for SuperSpeed ​​negative-polarity reception. This is the negative terminal of the SuperSpeed ​​differential pair received by the physical layer interface (PHY) chip. The SSTXP port is used for super-speed transmission of positive polarity signals. This is the positive side of the super-speed differential pair output by the physical layer interface (PHY) chip and is connected to the corresponding TX pin of the USB connector. The SSTXN port is used for super-speed transmission of negative polarity signals. This is the negative side of the super-speed differential pair output by the physical layer interface (PHY) chip.

[0051] The DP port is the USB 2.0 data positive terminal, representing the positive side (D+) of the standard USB 2.0 differential data line and directly connected to the D+ pin of the USB connector. The DM port is the USB 2.0 data negative terminal, representing the negative side (D-) of the standard USB 2.0 differential data line and directly connected to the D- pin of the USB connector. Note: The DP / DM port is responsible for USB 2.0 data transmission. For pure USB 3.1 physical layer interfaces like the TUSB1310A, the DP and DM ports pass input signals directly through without processing by the physical layer interface (PHY). Instead, these signals are assigned to a separate PHY controller dedicated to USB 2.0, reserved for this system. The VBUS port is the power supply pin on the USB interface, such as the +5V power pin. The R1EXT port is used to configure the signal port external resistor R1. This external resistor, typically with 1% accuracy, is connected. Its primary function is to set the bias current for the internal analog circuitry and to facilitate chip self-calibration, ensuring stable performance across various process, voltage, and temperature conditions. The R1EXTRTN port is used to configure the return path of the external resistor R1 of the signal port and needs to be directly connected to the analog ground. This pin provides a clean, low-noise return path for the bias current.

[0052] In some embodiments, the electronic sight mark generation device for a synoptophore further includes a power management circuit 107, connected to the sight mark generation module 105, the first display module, and the second display module, respectively, for managing power supply to the sight mark generation module 105, the first display module, and the second display module. For example, the core voltage domain of the Zynq-7000 FPGA master chip includes 1.5V for DDR3 memory power, 0.9V for core power, 1.2V for LPDDR2 memory power, 3.3V for I / O power, and 1.8V for auxiliary power. The first and second display modules receive a 12V drive power supply, and the interface circuit receives a 3.3V power supply. Based on this, the power management circuit 107 can select a 12V / 6A DC input and a TI TPS65910 power management chip for output. The power supply is protected by a transient voltage suppression diode (TVS diode) and a resettable fuse. The TVS diode protects the modules from voltage spikes.

[0053] In some embodiments, the electronic sight mark generating device for a synoptophore further includes a temperature sensor 108 connected to the sight mark generating module 105 for monitoring the temperature within the electronic sight mark generating device for a synoptophore. Temperature sensor 108 can be a DS18B20 sensor. The electronic sight mark generating device for a synoptophore in this embodiment employs a modular design, with the display module and control module separated, which helps reduce maintenance costs by, for example, 40%.

[0054] In some embodiments, the electronic sight mark generation device for a synoptometer further includes a human-computer interaction module 109 for setting the shape parameters and / or color parameters and / or motion parameters of the sight mark. Exemplarily, the human-computer interaction module 109 includes, but is not limited to, a keyboard or buttons. Through the human-computer interaction module 109, such as a keyboard or buttons, a doctor can select different test images and select parameters such as the shape, size, color, and motion trajectory of the sight mark via an interface control module. This allows the doctor to flexibly adjust the test image based on the specific circumstances and needs of the patient being tested. This personalized testing method significantly improves the sensitivity and specificity of ophthalmic examinations.

[0055] In some embodiments, the electronic sight mark generating device for a synoptophore further includes a housing, the housing being provided with a first mounting cavity and a second mounting cavity arranged side by side, the first mounting cavity being used to mount the first display module, and the second mounting cavity being used to mount the second display module. By structurally designing the housing, the electronic sight mark generating device for a synoptophore can be head-mounted, worn on the head of a subject, with the subject's left eye facing the first display module and right eye facing the second display module, respectively.

[0056] In some embodiments, the electronic sight mark generating device for the synoptophore further includes: a thermally conductive substrate, which is bonded to the first display module and the second display module, and the thermal conductivity of the thermally conductive substrate is greater than or equal to a preset value. The thermal conductivity of the thermally conductive substrate is greater than or equal to the preset value, so that the thermal conductivity of the thermally conductive substrate is relatively large, and the heat generated by the first display module and the second display module is conducted through the thermally conductive substrate, thereby improving the heat dissipation efficiency. The thermally conductive substrate can be bonded to the heating area of ​​the first display module and the heating area of ​​the second display module. Specifically, the thermally conductive substrate can be bonded to the first drive circuit module of the first display module and the second drive circuit module of the second display module. In some embodiments, the thermal conductivity of the thermally conductive substrate is ≥170 W / m·K, and the thermally conductive substrate can use an aluminum nitride ceramic substrate. The thermally conductive substrate can be bonded to the first display module and the second display module using thermally conductive adhesive.

[0057] In some embodiments, the electronic sight mark generation device for a synoptophore further includes a heat pipe disposed on a side of the thermally conductive substrate away from the first and second display modules, for conducting heat away from the thermally conductive substrate, thereby further improving heat dissipation efficiency. The heat pipe can contact the thermally conductive substrate, with heat from the thermally conductive substrate being transferred to the heat pipe and then conducted away along the heat pipe. The heat-absorbing section of the heat pipe contacts the area where the thermally conductive substrate and the heat-generating area meet, while the heat-dissipating section extends outward and reaches a heat sink. In practical applications, thermal adhesive is applied to one side of the thermally conductive substrate and aligned with the heat-generating area on the back of the first and second display modules. Based on the actual space available on the back of the first and second display modules, the heat pipe is heated with a heat gun and bent into a matching shape. Exemplarily, the heat pipe can be a micro copper tube, for example, with a diameter of 3 mm. The thermal adhesive can reduce contact thermal resistance and can be a highly thermally conductive silicone grease. The housing can be made of, but is not limited to, an aluminum alloy, which has the advantage of being lightweight. For example, 6061-T6 aluminum alloy can be used, weighing ≤300g. During the hardware implementation process in this embodiment, considerations such as heat dissipation, power consumption, and electromagnetic compatibility are also taken into account. A reasonable heat dissipation design can ensure that the system maintains stable performance during long-term operation, while a low-power design helps extend the system's service life and reduce energy consumption. Furthermore, electromagnetic compatibility considerations can ensure that the system operates normally in complex electromagnetic environments, avoiding interference with or being interfered with by other devices.

[0058] This design uses micro-OLED direct display to achieve high-resolution, low-latency dynamic sight mark display. Combined with FPGA image processing and synchronous control, it ensures real-time performance and accuracy, while also reducing costs through a modular architecture. Clinical validation has shown that this solution significantly outperforms traditional devices in diagnostic accuracy and patient compliance, making it suitable for precise diagnosis, treatment, and rehabilitation training for strabismus and amblyopia. Future integration with AR / VR technologies is possible to expand virtual scene training capabilities.

[0059] The working principle of the electronic sight mark generating device of the synoptophore is based on the combination of image processing technology and display technology. It generates and switches a variety of test images through preset algorithms and programs to comprehensively evaluate the patient's visual function. Its accuracy, fluency, flexibility and programmability make the electronic sight mark generating device of the synoptophore play an increasingly important role in ophthalmic examinations.

[0060] From the perspective of functional requirements, the core task of the electronic dynamic optotype generator of the synoptophore is to generate and display a variety of test images. These images should cover geometric patterns, letter symbols, and natural scenes, etc. to meet the needs of different ophthalmic examinations. For example, geometric patterns can be used to evaluate the basic visual function of patients, letter symbols can help check the reading ability and visual status of patients, and natural scene images can more realistically simulate daily life environment, thus more accurately evaluating the visual adaptation ability of patients.

[0061] In terms of performance indicators, the electronic dynamic optotype generator of the synoptophore has high resolution, high refresh rate, and low delay, etc. High resolution can ensure the clarity of test images, so that patients can more accurately identify image details; high refresh rate can ensure the smoothness of images, avoiding the influence of image switching on test results; low delay can ensure the quick response of the device to patient reactions, thus improving the accuracy and efficiency of the test.

[0062] The stability, reliability and ease of use of the system are also important requirements. Stability is related to the long-term operation and maintenance cost of the device, reliability directly affects the accuracy and reliability of the test results, and ease of use is related to the user experience and market promotion of the device. Therefore, in the design process, these factors need to be fully considered to ensure that the electronic dynamic optotype generator of the synoptophore can run stably in various environments, provide accurate and reliable test results, and provide users with a simple and clear operation interface and convenient user experience.

[0063] In the context of the continuous development of ophthalmic examination technology, the design and implementation of the electronic dynamic optotype generator of the synoptophore has become a key link to improve the level of ophthalmic diagnosis and treatment. By combining advanced image processing technology and ophthalmic medical knowledge, it provides ophthalmologists with a more powerful diagnostic tool, which helps to improve the accuracy of diagnosis and the effectiveness of treatment. At the same time, its small size, high integration, low cost, easy installation, maintenance and operation, etc. determine that the electronic dynamic optotype generator of the synoptophore will play a greater role in the future.

[0064] Potential drawbacks of traditional synoptophore optotype technology include: limited optotype types, difficulty updating, and potential wear and dirt from frequent use or improper storage, affecting display quality; inefficient and imprecise manual operation, impacting the accuracy of examination results; a lack of personalized optotypes, which cannot be quickly adjusted or customized according to the patient's specific situation, and insufficient dynamic effects, which limits the assessment and training of dynamic binocular vision function; static optotypes cannot comprehensively assess dynamic fusion and stereoscopic vision, and cannot effectively improve patients' binocular coordination ability in dynamic environments; and manual data recording and statistics affect diagnostic accuracy and are not conducive to long-term data storage and comparative analysis. Although digital synoptophore optotypes have improved upon the shortcomings of traditional technology, they still suffer from large size, inconvenient operation, low flexibility, and high purchase and maintenance costs.

[0065] In comparison, the Synoptophore electronic dynamic sight mark generator offers significant advantages and far-reaching significance. Its core value lies in its ability to provide richer and more varied test images, enabling a more comprehensive and accurate assessment of a patient's visual function. This innovation is not only crucial for the early detection of ophthalmic diseases, but also plays an indispensable role in the diagnosis and treatment process.

[0066] Specifically, the design of the synoptoscope's electronic dynamic optotype generator allows doctors to flexibly adjust the test image, including key parameters such as its shape, size, color, and motion trajectory, based on the patient's specific situation and needs. This personalized testing method greatly improves the sensitivity and specificity of eye examinations, helping doctors more accurately identify various eye problems, including but not limited to strabismus, amblyopia, and abnormal binocular vision. Especially in the early stages of a disease, when symptoms may not yet be apparent, the use of an electronic dynamic optotype generator can significantly improve diagnostic accuracy, thereby providing patients with more timely and effective treatment.

[0067] The use of the Synoptoscope electronic dynamic optotype generator has also promoted the development of intelligent and automated ophthalmic examination equipment. By integrating advanced computer technology, image processing technology, and machine vision technology, the Synoptoscope electronic dynamic optotype generator can automatically generate, display, and analyze test images, greatly improving the efficiency and convenience of ophthalmic examinations. This not only reduces the workload of doctors but also provides patients with a more comfortable and convenient examination experience. More importantly, the Synoptoscope electronic dynamic optotype generator is easy to install and carry, affordable, simple and flexible to operate, and easy to maintain. With the continuous advancement and innovation of technology, it is believed that future dynamic optotype generators will have higher performance, richer functions, and a wider range of application scenarios, injecting new vitality and momentum into the development of ophthalmology.
