The side facing the image plane is defined as the fourth surface, the side of the third lens facing the object plane is defined as the fifth surface, and the side facing the image plane is defined as the sixth surface. Then: the first surface is a plane with infinite curvature radius, the second surface is a convex image plane with a curvature radius equal to -49.930mm, the third surface is a convex object plane with a curvature radius equal to 53.440mm, the fourth surface is a convex image plane with a curvature radius equal to -49.000mm, the fifth surface is a convex object plane with a curvature radius equal to 52.510mm, and the sixth surface is a plane with infinite curvature radius.

DETAILED DESCRIPTION

[0037] See also Figures 1 to 5 The present invention provides an infrared endoscope transfer lens optical system suitable for imaging flowing blood, comprising an optical lens unit 101, an imaging unit 102, a power management unit 103, a user login unit 104, a storage unit 105 and a storage management unit 106;

[0038] The optical lens unit 101 is used to further magnify the image plane output by the front eyepiece and evenly transmit it to the rear imaging unit 102 for imaging refraction and focusing;

[0039] The imaging unit 102 is responsible for receiving and processing infrared radiation from the observed object, and finally generating a cleaned image;

[0040] The power management unit 103 is used to supply power to the optical lens unit 101, the imaging unit 102, the user login unit 104, the storage unit 105 and the storage management unit 106 respectively;

[0041] The user login unit 104 is responsible for verifying the user's identity information and access rights. When the user's identity information is successfully verified, the user will be allowed to access system resources. When the user's identity information verification fails, the user will be denied access.

[0042] The storage unit 105 independently stores the image generated by the imaging unit 102 and also independently stores the user's operation process;

[0043] The storage management unit 106 is used to manage the resources of the storage unit 105 and authenticate the user who needs to edit, copy or transfer information, and the authentication of the storage management unit 106 is independent of the authentication of the user login unit 104 .

[0044] In this embodiment, the optical lens unit 101 focuses the infrared radiation emitted by the observed object through the lens group arrangement and transmits it to the imaging unit 102. In the imaging unit 102, the intensity and angle of the incident light are adjusted to generate a digital image. The power management unit 103 supplies power to the optical lens unit 101, the imaging unit 102, the user login unit 104, the storage unit 105 and the storage management unit 106 respectively. At the same time, when using the optical system, it is necessary to log in to an account through the user login unit 104, and perform operation control according to the authority corresponding to the account. The storage unit 105 independently stores the observed digital image, and also traces and stores the user's operation content to facilitate subsequent tracking and tracing of the operation content. The storage management unit 106 locks and manages the stored content, and the corresponding account must be verified before the content in the storage unit 105 can be viewed, copied, transferred and external devices.

[0045] Further, the imaging unit 102 includes an infrared radiation receiving module 107, a lens group focusing module 108, an aperture adjustment module 109 and an image sensor conversion module 110;

[0046] The infrared radiation receiving module 107 is used to receive infrared radiation emitted by the observed object and enter the imaging unit 102;

[0047] The lens group focusing module 108 is used to refract and focus after receiving the infrared radiation so that it can form a clear image on the image sensor;

[0048] The aperture adjustment module 109 adjusts the intensity and angle of the incident light according to the observation requirements to control the exposure and depth of field of the image;

[0049] The image sensor conversion module 110 is used to convert the focused infrared radiation into an electrical signal, and the converted electrical signal can generate a digital image after being processed.

[0050] In this embodiment, the infrared radiation receiving module 107 receives infrared radiation, and in the lens group focusing module 108, the imaging quality and resolution of the system are improved, and the deviation and distortion of the lens are reduced through a reasonable lens combination and arrangement. The exposure and depth of field of the image are controlled by the aperture adjustment module 109, and the background noise and interference are reduced. Finally, the image sensor conversion module 110 converts the focused infrared radiation into an electrical signal, and the processed electrical signal can generate a digital image.

[0051] Furthermore, the user login unit 104 includes a front-end module 111, a back-end processing module 112, a database 113 and a security module 114;

[0052] The front-end module 111 provides the user with an input box for username and password;

[0053] The backend processing module 112 is used to compare the input user name and password with the data content in the database 113 to verify the user identity information;

[0054] The database 113 stores and records the user's username, password, role, authority, user information and registration time;

[0055] The security module 114 encrypts the database 113 to prevent the user name and password from being cracked by brute force.

[0056] In this embodiment, the front-end module 111 allows the user to input the user name, password and verification code, and the confirmed user name, password and verification code are transmitted to the back-end processing module 112. The back-end processing module 112 verifies the user name and password with the database 113. While the database 113 verifies that the user name is correct, it determines the corresponding user's usage rights. The security module 114 encrypts and protects the storage and verification of the user name and password, and also encrypts and protects the acceptance and sending of the verification code to ensure the stability of user data.

[0057] Furthermore, the front-end module 111 provides an input box for the user to input a user name and password, and prevents automated attacks through a verification code input box. It also provides a submit button, which triggers a login request after the user clicks it. The front-end module 111 also includes an error prompt, which displays error information when the login fails, including incorrect username or password, and incorrect verification code.

[0058] In this embodiment, the front-end module 111 provides the user with an input environment for the user name, password and verification code, and transmits the input user name, password and verification code to the back-end processing module 112 accordingly, and also provides the user with relevant prompt information if the user name or password is incorrect or the verification code is incorrect.

[0059] Furthermore, the back-end processing module 112 receives the user name and password transmitted by the front-end module 111, compares the user name and password with the user information stored in the database 113, verifies the user identity information, and determines whether the user has the authority to access system resources based on the verified role identity information. At the same time, the error code corresponding to the error information after the user name and password verification is returned to the front-end module 111.

[0060] In this embodiment, the back-end processing module 112 receives the data content input by the front-end module 111, verifies the received data content with the data content stored in the database 113, and sends the verified information data to the front-end module 111. If the verification is correct, the next step can be performed. If the verification is wrong, the corresponding error prompt information will be displayed in the pop-up window of the front-end module 111 interface.

[0061] Furthermore, the security module 114 encrypts the password, and when storing the user password in the database 113, encryption technology is used for processing. The password is also protected by encryption technology during transmission, and login records are logged for analysis and security auditing. At the same time, when the number of errors exceeds a preset value, the account is locked or a verification code verification is added.

[0062] In this embodiment, the security module 114 performs security management on the input data and the verified data, encrypts the data, and improves the security and stability of the user data.

[0063] Further, the storage unit 105 includes an image storage module 115 and a user storage module 116;

[0064] The image storage module 115 is used to store the digital image after imaging;

[0065] The user storage module 116 performs source tracing and storage of the operation content after the user logs in.

[0066] In this embodiment, the storage unit 105 stores the digital image and the user operation traceability content separately and independently through the image storage module 115 and the user storage module 116, which can improve the stability and security of the stored data, while also improving the storage efficiency and response rate, and can better store the relevant data content.

[0067] Furthermore, the power management unit 103 includes a power supply module 117, a power switching module 118, a battery module 119 and a power protection module 120;

[0068] The power supply module 117 is used to connect to the power supply end and convert the current and voltage into the required current and voltage;

[0069] The power switching module 118 is used to automatically switch the power supply when the device switches from the power supply of the battery module 119 to the external power supply or from the external power supply to the battery module 119;

[0070] The battery module 119 is used to power the device and can be used as a backup power source to ensure normal operation when the external power source is cut off;

[0071] The power protection module 120 is used to detect the temperature, voltage and current parameters of the battery module 119 and take corresponding protection measures under abnormal circumstances to ensure the stable operation and safety of the equipment.

[0072] In this embodiment, the power supply module 117 provides external power to the battery module 119, and the power protection module 120 is connected to the output end of the battery module 119 to protect the battery module 119. The power switching module 118 is arranged between the power protection module 120 and the battery module 119 to automatically switch the power supply mode of the battery module 119, thereby improving the intelligence of system use.

[0073] Furthermore, the battery module 119 includes a main battery 121 and a sub-battery 122, and the number of the sub-batteries 122 is multiple groups, and the multiple groups of sub-batteries 122 are electrically connected to the main battery 121 respectively, and the main battery 121 and each group of sub-batteries 122 are respectively connected to the optical lens unit 101, the imaging unit 102, the user login unit 104, the storage unit 105 and the storage management unit 106 for power supply.

[0074] In this embodiment, the main battery 121 provides backup power for the system. When an external power source is connected, neither the main battery 121 nor the sub-battery 122 operates, and the external power source directly powers the system. When the external power source has no power supply, the main battery 121 provides unified power supply to the system. When the main battery 121 has no power supply or the connection between the main battery 121 and the system unit is abnormal, the sub-battery 122 provides independent power supply to the corresponding system unit.

[0075] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
