[0040] This embodiment provides an electronic flexible mirror system 10. Figure 1 This is a schematic diagram of the electronic flexible mirror system 10 in this embodiment. Figure 1 As shown, the electronic flexible microscope system 10 includes an image sensor 111, an amplitude enhancement circuit 112, an amplitude reduction circuit 131, a transmission cable 12, and a signal resolver 132; the transmission cable 12 includes a clock signal wire 121; wherein: the input terminal of the image sensor 111 is connected to the output terminal of the amplitude enhancement circuit 112; the input terminal of the amplitude enhancement circuit 112 and the output terminal of the amplitude reduction circuit 131 are connected through the clock signal wire 121; the input terminal of the amplitude reduction circuit 131 is connected to the clock signal output terminal of the signal resolver 132.

[0041] Specifically, the amplitude enhancement circuit 112 can be any circuit structure composed of electronic components such as resistors, capacitors, and diodes capable of increasing the amplitude of a signal. For example, the amplitude enhancement circuit 112 can be a level converter chip capable of converting a low level to a high level, or a differential-to-single-ended chip capable of converting two differential signals with the same amplitude but opposite phase into a single-ended signal. Furthermore, the amplitude enhancement circuit 112 can also be other circuit structures adapted by those skilled in the art based on actual application scenarios; this embodiment does not impose specific limitations. Similarly, the amplitude reduction circuit 131 can be implemented by a level converter chip capable of converting a high level to a low level, or a single-ended-to-differential chip capable of converting one clock signal into two differential signals with opposite phase and equal amplitude.

[0042] In the electronic flexible mirror system 10 of this embodiment, the amplitude enhancement circuit 112 and the amplitude reduction circuit 131 are respectively disposed at the input terminal of the image sensor 111 and the output terminal of the signal analyzer 132. The clock signal generated by the signal analyzer 132 is processed by the amplitude reduction circuit 131 before entering the transmission cable 12, and then transmitted to the image sensor 111 through the clock signal wire 121 of the transmission cable 12. Before being received by the image sensor 111, the amplitude is restored by the amplitude enhancement circuit 112.

[0043] By reducing the amplitude of the clock signal generated by the signal analyzer 132 through the amplitude reduction circuit 131, the amplitude of the clock signal within the transmission cable 12 can be reduced, thereby reducing the phenomenon of crosstalk between the clock signal and the analog signal within the transmission cable 12, and thus reducing the probability of image abnormalities caused by cable crosstalk. The amplitude enhancement circuit 112 enhances the amplitude of the clock signal before it enters the image sensor 111, restoring the amplitude of the clock signal to a level that can be recognized by the image sensor, thereby enabling the normal operation of the image sensor 111. Compared to related technologies that reduce cable crosstalk by enhancing the shielding performance of the transmission cable of the flexible microscope or by adding capacitors and resistors to the clock signal, this embodiment only requires the addition of an amplitude processing circuit, which has lower requirements for cable manufacturing processes, resulting in lower equipment costs. Furthermore, the flexible microscope system provided in this embodiment does not affect the waveform of the clock signal, thus avoiding the problem of the image sensor being unable to recognize the clock signal and affecting the normal operation of the image sensor.

[0044] In addition, such as Figure 1As shown, the transmission cable 12 in this embodiment may further include an analog signal conductor 122, used to send the analog signal generated by the image sensor 111 to the signal analyzer 132 for analysis, thereby obtaining the image information acquired by the image sensor 111. Additionally, the transmission cable 12 may also include a power supply conductor 123 and a grounding conductor 124. The power supply port of the signal analyzer 132 is connected to the power input terminal of the image sensor 111 via the power supply conductor 123 to power the image sensor 111. Further, by... Figure 1 It can also be seen that the image sensor 111 and the amplitude enhancement circuit 112 can be installed in the flexible lens handle 11 of the flexible lens system 10. The amplitude reduction circuit 131 and the signal analyzer 132 can be installed in the processor 13 of the flexible lens system.

[0045] For example, the image sensor 111 is located at the front end of the flexible lens handle 11. The front end of the flexible lens handle 11 may also include, but is not limited to, an illumination component, a temperature sensor, etc. One or more components at the front end of the flexible lens handle 11 are encapsulated within the flexible lens handle 11 and connected to the signal resolver 132 via a signal line. Additionally, the aforementioned flexible lens handle 11 may also include an operating section. This operating section may be equipped with function buttons and / or a handwheel, used to control the position and orientation of the image sensor 111. The operator adjusts the position and orientation of the image sensor 111 within the detection area via the operating section to achieve image acquisition within the detection area. Based on the aforementioned connection with the signal resolver 132, the image sensor 111 performs normal operation within the detection area. The image sensor 111 transmits the acquired image information as an analog signal to the signal resolver 132 via the analog signal wire 122 in the transmission cable 12. The signal resolver 132 analyzes the analog signal and presents the analyzed image information on the display component of the processor 13, thereby displaying the image detected by the image sensor 111 within the detection area. During the transmission of analog signals, the electronic soft lens system 10 of this embodiment processes the amplitude of the clock signal output by the signal analyzer 132, resulting in a lower amplitude of the clock signal transmitted within the transmission cable 12. This reduces crosstalk between the clock signal and the analog signal within the transmission cable 12, thereby reducing image stripe interference caused by cable crosstalk.

[0046] Additionally, the image sensor 111 in the aforementioned flexible lens system 10 may include any type of sensor for capturing images of the interior of a flexible cavity. For example, a charge-coupled device (CCD) sensor or a complementary metal-oxide-semiconductor (CMOS) sensor may be selected.

[0047] The signal resolver 132 described above can be any signal resolution component in a processor, combining software modules and hardware structures, used for resolving analog signals. The processor 13 may also include one or more processor components and a storage component for storing data. The processing components may include, but are not limited to, microprocessors (MCUs) or programmable logic devices (FPGAs). The processor 13 may also include transmission components for communication functions and input / output components. Those skilled in the art will understand that this embodiment does not limit the structure of the signal resolver 132 and the processor 13. For example, the processor 13 may include more or fewer components.

[0048] Furthermore, the storage unit in processor 13 can be used to store computer programs, such as application software programs and modules. The processing unit executes various functional applications and data processing by running the computer programs stored in the storage unit. The storage unit may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the storage unit may further include storage components remotely located relative to the processing unit, which can be connected to processor 13 via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0049] The aforementioned flexible electronic microscope system includes an image sensor, an amplitude enhancement circuit, an amplitude reduction circuit, a transmission cable, and a signal resolver. The transmission cable includes a clock signal conductor. The input terminal of the image sensor is connected to the output terminal of the amplitude enhancement circuit. The input terminal of the amplitude enhancement circuit and the output terminal of the amplitude reduction circuit are connected via the clock signal conductor. The input terminal of the amplitude reduction circuit is connected to the output terminal of the clock signal in the signal resolver. This system can reduce the amplitude of the clock signal transmitted through the transmission cable and restore the amplitude of the clock signal before it is received by the image sensor. Therefore, it can reduce crosstalk between the clock signal and the analog signal in the transmission cable at a lower equipment cost and without affecting the clock signal waveform.

[0050] Furthermore, in one embodiment, the amplitude conversion circuit includes a level-up conversion circuit, and the amplitude conversion circuit includes a level-down conversion circuit; wherein: the input terminal of the image sensor is connected to the output terminal of the level-up conversion circuit; the input terminal of the level-up conversion circuit and the output terminal of the level-down conversion circuit are connected through a clock signal wire; and the input terminal of the level-down conversion circuit is connected to the output terminal of the clock signal in the signal analyzer.

[0051] Figure 2 This is a schematic diagram of the electronic flexible mirror system 20 based on a level conversion circuit in this embodiment. Wherein, as... Figure 2As shown, the electronic flexible microscope system 20 includes: a flexible microscope handle 21, a transmission cable 22, and a processor 23. The flexible microscope handle 21 houses an image sensor 211 and a level-up conversion circuit 212, while the processor 23 includes a level-down conversion circuit 231 and a signal analyzer 232. Additionally, [the system is described in the original text]. Figure 2 It can also be seen that the transmission cable 22 may include a clock signal wire 221, an analog signal wire 222, a power supply wire 223, and a ground wire 224. Exemplarily, the level-up conversion circuit 212 and the level-down conversion circuit 231 of this embodiment can be implemented based on diodes, transistors, or field-effect transistors (MOSFETs). Alternatively, those skilled in the art can also select level-up chips, such as SN74AXC4T245PWR and TXS0108EZXYR, based on actual application requirements. This embodiment does not specifically limit this.

[0052] The clock signal generated by signal analyzer 232, after entering the input of the down-level conversion circuit 231, is down-leveled by the down-level conversion circuit 231 before being output from the output of the down-level conversion circuit 231 and transmitted to the up-level conversion circuit 212 via the clock signal wire 221 in the transmission cable 22. Therefore, the amplitude of the clock signal processed by the down-level conversion circuit 231 is lower, thereby reducing crosstalk between the clock signal and the analog signal in the transmission cable 22. Furthermore, before the image sensor 211 receives the clock signal, this down-leveled clock signal enters the up-level conversion circuit 212 from its input. After the up-level conversion circuit 212 restores the clock signal's level, the restored clock signal is transmitted from its output to the input of the image sensor 211. The image sensor 211 can receive the amplitude-restored clock signal, facilitating image sensor recognition. Therefore, this embodiment can eliminate cable crosstalk by adding only two level conversion circuits to the electronic flexible microscope system, with low requirements for cable manufacturing processes, no increase in cable costs, and no impact on the clock signal waveform. Thus, this embodiment can reduce crosstalk between the clock signal and analog signal in the transmission cable at a lower equipment cost and without affecting the clock signal waveform.

[0053] In another embodiment, the amplitude enhancement circuit includes a differential-to-single-ended circuit; the amplitude reduction circuit includes a single-ended-to-differential circuit; the clock signal conductor includes a first clock signal conductor and a second clock signal conductor; wherein: the output terminal of the clock signal in the signal resolver is connected to the input terminal of the single-ended-to-differential circuit; the output terminal of the first differential signal in the single-ended-to-differential circuit is connected to the input terminal of the first differential signal in the differential-to-single-ended circuit via the first clock signal conductor; the output terminal of the second differential signal in the single-ended-to-differential circuit is connected to the input terminal of the second differential signal in the differential-to-single-ended circuit via the second clock signal conductor; and the output terminal of the differential-to-single-ended circuit is connected to the input terminal of the image sensor.

[0054] Figure 3 This is a schematic diagram of the electronic flexible mirror system 30 based on a differential / single-ended conversion circuit in this embodiment. Figure 3 As shown, the flexible microscope system 30 includes a flexible microscope handle 31, a transmission cable 32, and a processor 33. The flexible microscope handle 31 may house an image sensor 311 and a differential-to-single-ended circuit 312; the processor 33 may house a single-ended-to-differential circuit 331 and a signal resolver 332. The transmission cable 32 may include a first clock signal conductor 321 for transmitting a first differential signal, a second clock signal conductor 322 for transmitting a second differential signal, an analog signal conductor 323 for transmitting an analog signal, a power supply conductor 324, and a grounding conductor 325.

[0055] The aforementioned single-ended to differential circuit 331 can be any circuit structure capable of converting a single-ended signal to a differential signal. For example, the single-ended to differential circuit 331 can be composed of operational amplifiers, inverting amplifier circuits, and resistors, or it can be implemented using a dedicated single-ended to differential chip, such as the SN65LVDS049PW or AD8476. The aforementioned differential to single-ended circuit 312 can be any circuit structure capable of converting a differential signal to a single-ended signal, composed of resistors, amplifiers, and other components. Similarly, the differential to single-ended circuit 312 can be implemented based on chips such as the SN65LVDS049PW or NJM2507RB1. This embodiment does not impose specific limitations.

[0056] The clock signal generated by the signal resolver 332 enters the single-ended to differential converter 331 from its input. After processing by the converter, it is split into two differential signals with equal amplitude and opposite phase, namely the first differential signal and the second differential signal. Understandably, the amplitudes of the first and second differential signals are lower than the amplitude of the clock signal generated by the signal resolver 332. Therefore, the processing of the clock signal by the single-ended to differential converter 331 reduces the amplitude of the clock signal in the transmission cable.

[0057] Specifically, the first differential signal is output through the first output terminal of the single-ended to differential circuit 331 and transmitted to the differential to single-ended circuit 312 via the first clock signal wire 321. The second differential signal is output through the second output terminal of the single-ended to differential circuit 331 and transmitted to the differential to single-ended circuit 312 via the second clock signal wire 322. The two input terminals of the differential to single-ended circuit 312 receive the first differential signal and the second differential signal, respectively. The differential to single-ended circuit 312 performs conversion processing on the received first differential signal and second differential signal, and outputs a single-ended clock signal to the image sensor 311. This output single-ended clock signal is the amplitude-recovered clock signal. In this embodiment, by performing single-ended to differential processing on the clock signal, the amplitude of the clock signal can be reduced; and by performing differential to single-ended processing on the first differential signal and the second differential signal, an amplitude-recovered clock signal can be obtained. Therefore, this embodiment can reduce the amplitude of the clock signal transmitted in the transmission cable based on the single-ended / differential conversion circuit, thereby eliminating the crosstalk of the clock signal to the analog signal in the transmission cable. Compared with related technologies, this embodiment can eliminate cable crosstalk with lower equipment cost and without affecting the clock signal waveform.

[0058] Furthermore, in one embodiment, the first differential signal and the second differential signal are two clock signals with equal amplitude and opposite phase.

[0059] Furthermore, in one embodiment, based on the aforementioned flexible electronic microscope system 10, the transmission cable 12 further includes an analog signal conductor 122; the output end of the image sensor 111 and the input end of the analog signal in the signal resolver 132 are connected via the analog signal conductor 122. The analog signal output by the image sensor 111 can be transmitted to the signal resolver 132 via the analog signal conductor 122, and thus be resolved by the signal resolver 132.

[0060] In another embodiment, based on the above-described electronic flexible mirror system 10, the transmission cable 12 further includes a power supply wire 123; the power supply port of the signal analyzer 132 and the power input terminal of the image sensor 111 are connected through the power supply wire 123.

[0061] In another embodiment, based on the above-described electronic flexible mirror system 10, the transmission cable 12 further includes a grounding wire 124; the grounding terminal of the signal analyzer 132 and the grounding terminal of the image sensor 111 are connected through the grounding wire 124.

[0062] In one embodiment, based on the aforementioned flexible microscope system 10, the image sensor 111 and the amplitude enhancement circuit 112 are disposed in the flexible microscope handle 11 of the flexible microscope system 10. This embodiment, by adding an amplitude enhancement circuit to the flexible microscope handle, enables amplitude recovery of the clock signal at a lower equipment cost, avoiding any impact on the waveform of the clock signal, thereby allowing the image sensor to successfully identify the clock signal transmitted via the transmission cable.

[0063] In one embodiment, based on the aforementioned flexible electronic microscope system 10, the amplitude reduction circuit 131 and the signal resolver 132 are disposed in the processor 13 of the flexible electronic microscope system. This embodiment, by placing the amplitude reduction circuit within the processor, can reduce the amplitude of the clock signal output by the signal resolver at a lower hardware cost, thereby achieving cable crosstalk elimination at a lower equipment cost.

[0064] Additionally, based on the aforementioned flexible electronic microscope system 10, the processor 13 also includes a display component. This display component can display the image information detected by the image sensor within the detection area in real time, thereby facilitating the operator to complete the detection of the flexible electronic microscope within the detection area based on the image information.

[0065] This embodiment provides a signal processing method. Figure 4 This is a flowchart of the signal processing method in this embodiment, as shown below. Figure 4 As shown, the process includes the following steps:

[0066] In step S410, the signal resolver sends the generated clock signal to the image sensor sequentially via the amplitude reduction circuit, the transmission cable, and the amplitude increase circuit, and receives the analog signal acquired by the image sensor. During the transmission of the clock signal: the amplitude reduction circuit performs amplitude reduction processing on the received initial clock signal; the amplitude increase circuit performs amplitude recovery processing on the received amplitude-reduced clock signal.

[0067] By taking the above steps, the amplitude of the clock signal transmitted in the transmission cable can be reduced, and the amplitude of the clock signal can be restored before the image sensor receives it. Therefore, it is possible to reduce the crosstalk between the clock signal and the analog signal in the transmission cable with lower equipment cost and without affecting the waveform of the clock signal.
