Description

[Technical field]

[0001] The present invention relates generally to calibration tools, and more particularly to calibration tools for optical diagnostic systems. [Background technology]

[0002] Ophthalmologists routinely handle optical diagnostic devices to examine patients' eyes. In many cases, the optical diagnostic devices are regularly calibrated using a calibration tool (such as a test body, test eye, calibration target, or reference body) to ensure that the optical diagnostic device provides accurate measurements. Therefore, the calibration tool is manufactured and measured with high precision. Due to the high precision required for the calibration tool, the repeatability of the calibration tool varies depending on the manufacturing conditions. As a result of this variation, one calibration tool with a given set value / nominal value is usually assigned directly to a diagnostic system, and another calibration tool cannot be used with that system. This may result in additional costs and reduce accuracy, especially if the assigned calibration tool is lost or the wrong tool is used, increasing the cost and complexity of maintenance and repair of the optical diagnostic system. Summary of the Invention [Means for solving the problem]

[0003] A calibration tool is disclosed. In one or more embodiments, the calibration tool includes at least one pupil configured to receive light emitted from an optical diagnostic system and to reflect light back to the optical diagnostic system. The calibration tool further includes a machine-readable label including information for calibrating the optical diagnostic system, the machine-readable label being disposed over the at least one pupil.

[0004] A method of calibrating an optical diagnostic system with a calibration tool is disclosed. The method includes registering and aligning the optical diagnostic system with the calibration tool. The method further includes scanning a machine-readable label disposed on at least one pupil of the calibration tool using the optical diagnostic system. The method further includes storing a set value obtained from the machine-readable label in a storage medium of the optical diagnostic system. The method further includes measuring an actual value of the at least one pupil. The method further includes comparing the actual value to the set value. The method further includes determining that the actual value is within an acceptable range of the set value.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0007] The present disclosure is directed to a calibration tool for optical diagnostic systems. More specifically, embodiments of the present disclosure are directed to a calibration tool configured to calibrate multiple optical diagnostic systems in a semi-automated manner.

[0008] The calibration of the optical diagnostic system is performed using a calibration tool with a pupil that mimics the pupil of the eye. The pupil of the calibration tool has fixed parameters (such as a set value, a nominal value, an axial length of the pupil, a diameter of the pupil, a radius of curvature of the eye, or a refractive error). An embodiment of the present disclosure allows one calibration tool to calibrate multiple optical diagnostic systems with a machine-readable label placed on the pupil of the calibration tool. The machine-readable label includes information about the calibration (such as a serial number of the calibration tool, a product number of the calibration tool, and fixed parameters of the pupil).

[0009] Additionally, embodiments of the present disclosure are directed to a method of calibrating an optical diagnostic system using a calibration tool. More specifically, embodiments of the present disclosure are directed to a method of calibrating an optical diagnostic system using a calibration tool by: (a) registering and aligning the optical diagnostic system with the calibration tool, (b) using the optical diagnostic system to scan a machine-readable label disposed on at least one pupil of the calibration tool, (c) storing a set value obtained from the machine-readable label in a storage medium of the optical diagnostic system, (d) measuring an actual value of the pupil at the calibration tool, (e) comparing the actual value with the set value, and (f) determining that the actual value is within an acceptable range of the set value.

[0010] Referring now to the description and drawings, exemplary embodiments of the disclosed devices, systems, and methods are shown in detail.

[0011] 1A illustrates a calibration tool 100 according to an embodiment of the present disclosure. The calibration tool 100 may be suitable for calibrating multiple optical diagnostic systems. For example, the calibration tool 100 may be suitable for calibrating a first optical diagnostic system that may be at location A and a second optical diagnostic system that may be at location B. This avoids the need for a specific separate calibration tool for each separate optical diagnostic system. In this regard, an embodiment of the present disclosure allows for calibrating at least two optical diagnostic systems that are not at the same physical location.

[0012] In one embodiment, the calibration tool 100 includes a pupil 102. For example, the pupil 102 of the calibration tool 100 may include at least one pupil 102 configured to receive light suitable for measuring a patient's eye using an optical diagnostic system. For example, the light received on the pupil 102 may be illuminated from the optical diagnostic system. The pupil 102 may reflect the light back to the optical diagnostic system.

[0013] In some embodiments, the calibration tool 100 may include parts similar to the human eye to accurately calibrate the optical diagnostics. For example, the calibration tool 100 may have a pupil 102 that includes features that mimic the human eye, such as a rod lens or an eyeball. In this example, the structure of the pupil 102 of the calibration tool 100 mimics the human eye such that the pupil 102 receives light from and reflects the light to the optical diagnostic system in the same way as the human eye.

[0014] It should be noted that while the pupil 102 shown in FIG. 1A may include two pupils, such a configuration is provided for illustrative purposes only. Embodiments of the present disclosure may be configured to include only one (FIG. 1B) or three or more pupils. Additionally, it should be noted that while the pupil 102 shown in FIG. 1A is aligned horizontally, such a configuration is provided for illustrative purposes only. Embodiments of the present disclosure may be configured to align the pupil 102 vertically or in any other orientation. The number and orientation of the pupils 102 may vary based on the requirements of the optical diagnostic system or to facilitate manufacturing or durability of the calibration tool 100.

[0015] In one embodiment, the calibration tool 100 includes a machine-readable label 104. For example, the machine-readable label 104 may be a barcode, such as a Data Matrix code, that includes information for performing a calibration of the optical diagnostic system. For example, the barcode of the machine-readable label 104 may be a Data Matrix barcode, such as a two-dimensional barcode. In another example, the barcode of the machine-readable label 104 may be a linear barcode, such as a one-dimensional barcode.

[0016] The machine-readable label 104 of the calibration tool 100 may be placed on the pupil 102 such that the machine-readable label 104 may be read by an optical diagnostic system. For example, the machine-readable label 104 may be placed on a surface proximate to the pupil 102, as shown in FIG. 1A.

[0017] The machine-readable label 104 of the calibration tool 100 may include information for calibrating the optical diagnostic system. For example, the information included in the machine-readable label 104 may include a serial number of the calibration tool, a product number of the calibration tool, a set value, a nominal value, an axial length of the eye in the calibration tool, a diameter of the pupil of the calibration tool, a radius of curvature of the eye in the calibration tool, or a refractive error of the eye in the calibration tool. The length of the rod lens is a reference standard for the axial length of the pupil, and the radius of curvature of the eye is a reference standard for the radius of curvature of the cornea. When the machine-readable label 104 is scanned by a camera of the optical diagnostic system, the information for calibrating the optical diagnostic system may be stored in a storage medium of the optical diagnostic system. In this regard, the information included in the machine-readable label 104 is specific to one calibration tool 100. This specificity of the information may be due to the high precision exhibited by the calibration tool.

[0018] In some embodiments, the machine-readable label 104 of the calibration tool 100 may communicate with the optical diagnostic system using radio frequency technology. For example, the radio frequency technology used for the machine-readable label 104 of the calibration tool 100 may include radio frequency identification (RFID) or near field communication (NFC).

[0019] It should be noted that while the machine-readable label 104 shown in FIG. 1A is disposed on only one of the two pupils, such a configuration is provided for illustrative purposes only. An embodiment of the present disclosure may be configured to have multiple machine-readable labels 104 for the calibration tool 100. For example, a first machine-readable label may be disposed on a first pupil, while a second machine-readable label may be disposed on a second pupil. As described above, each pupil is provided with a unique machine-readable label. In a configuration where there are a total of two pupils with unique machine-readable labels, one of the two pupils may be used as a backup pupil. For example, if a first calibration fails with the first pupil, a further calibration of the optical diagnostic system may be performed using the second pupil. As another example, a calibration tool with two different machine-readable labels may allow two optical diagnostic systems to be calibrated simultaneously.

[0020] In one embodiment, the calibration tool 100 includes a body assembly 106 configured to stabilize the pupil 102. For example, the pupil 102 may be supported by the body assembly 106 as shown in FIG. 1A. The pupil 102 may be fixed on a surface of the body assembly 106. For example, the pupil may be fixed to an upper portion of the body assembly. The body assembly 106 may be in at least partial direct contact with the pupil 102. As another example, the body assembly 106 and the pupil 102 may be integrated together to stabilize the pupil. For example, the pupil 102 may be integrated into the body assembly 106 such that the pupil 102 may be embedded within the body assembly 106.

[0021] In one embodiment, the calibration tool 100 includes a rod 108 that is secured to a chin rest bar holder 206 of the optical diagnostic system. The chin rest bar of the optical diagnostic system is where the patient places his or her chin when the ophthalmologist examines the patient's eye. Calibration for an optical diagnostic system is typically performed by first securing the calibration tool 100 onto the chin rest bar holder 206 of the optical diagnostic system. In this regard, the rod 108 of the calibration tool 100 securely secures the calibration tool 100 to the optical diagnostic system. The rod 108 of the calibration tool 100 may be used together with a body assembly 106 as shown in FIG. 1A. For example, a central portion of the rod 108 may be covered by the body assembly 106. This may allow the body assembly 106 to slide horizontally to adjust its position relative to the optical diagnostic system so that the pupil 102 is aligned with the camera of the optical diagnostic system.

[0022] Although both the rod 108 and the body assembly 106 shown in FIG. 1A are used in the calibration tool 100, such a configuration is provided for illustrative purposes only. An embodiment of the present disclosure may be configured to use only the rod 108 to stabilize the pupil 102, as shown in FIG. 1B. FIG. 1B illustrates another calibration tool according to another embodiment of the present disclosure. The body assembly 106 may be omitted, so long as the pupil 102 is securely attached to the chin rest bar holder 206 of the optical diagnostic system for calibration. Instead, the rod 108 may support the pupil 102.

[0023] FIG. 2 generally illustrates a calibration setup of an optical diagnostic system 200 using a calibration tool 100, according to one or more embodiments of the present disclosure. The calibration tool 100 is configured to calibrate the optical diagnostic system 200. For example, the calibration tool 100 may be securely attached to a chin rest bar holder 206 of the optical diagnostic system 200. A lens of the pupil may face toward a camera 202 of the optical diagnostic system 200, which allows a machine-readable label placed on a pupil 102 of the calibration tool 100 to be scanned by the optical diagnostic system 200. The machine-readable label on the pupil 102 is at a specific height from a reference point, such as a floor. The height of the camera 202 of the optical diagnostic system 200 is aligned with the height of the machine-readable label. The position of the calibration tool 100 is also aligned with the optical diagnostic system 200, such that the optical diagnostic system 200 may scan at least one pupil 102. If the height of the machine-readable label of calibration tool 100 and the height of the camera of optical diagnostic system 200 are not properly aligned, the height, position, or both of calibration tool 100 may be adjusted. For example, the height of calibration tool 100 may be adjusted by raising or lowering the calibration tool on chin rest bar holder 206. In another example, the position of calibration tool 100 may be adjusted by sliding the body assembly of calibration tool 100 or moving the position of chin rest bar holder 206.

[0024] In one embodiment, the optical diagnostic system 200 includes a monitor 204. The monitor 204 of the optical diagnostic system 200 may show a calibration procedure, a control measurement wizard for the calibration, an image captured from the camera 202, or a diagnostic related window. For example, when a user starts a calibration process, a control measurement wizard may appear on the monitor 204, and within the wizard, there may be specific instructions on how to proceed with the calibration. As another example, when the machine-readable label of the calibration tool 100 is scanned by the camera 202 of the optical diagnostic system 200, the control measurement wizard may automatically open and information stored on the machine-readable label may be displayed on the monitor 204. The monitor 204 of the optical diagnostic system 200 may also show windows unrelated to the calibration process, such as web browsing, video streaming, gaming, and general computer use.

[0025] In some embodiments, the optical diagnostic system 200 includes a storage medium that includes calibration data. The optical diagnostic system 200 also includes a processor coupled to the storage medium. The processor is configured to compare data acquired by the optical diagnostic system camera (e.g., actual values) with data included in a machine-readable label of the calibration tool (e.g., set values / nominal values). The processor is also configured to determine whether the calibration was successful based on the data acquired by the optical diagnostic camera, the data included in the machine-readable label, and a previously established tolerance range for the calibration.

[0026] FIG. 3 generally illustrates a control measurement wizard 300 used to calibrate an optical diagnostic system, according to one or more embodiments of the present disclosure. The control measurement wizard 300 is a user interface implemented in the optical diagnostic system that guides a user through a series of well-defined calibration steps. For example, the control measurement wizard 300 can prompt a user to scan a machine-readable label 104 placed on the pupil 102 to begin a calibration process for the optical diagnostic system. Once the machine-readable label is scanned and the relevant information is stored in the storage medium of the optical diagnostic system, the optical diagnostic system measures an actual value. The optical diagnostic system then compares the actual value measured by the optical diagnostic system with a set value from the machine-readable label to determine whether the calibration was performed successfully. In this regard, the implementation of the control measurement wizard 300 in the calibration steps makes the process more accessible and allows for daily or weekly calibration. Once the user aligns the camera of the optical diagnostic system with the pupil and the machine-readable label of the calibration tool, the remaining calibration steps can be semi-automatic in that minimal user interaction is required. In this sense, embodiments of the present disclosure may enable automatic calibration of optical diagnostic systems.

[0027] Although an initial screen for the calibration step on the control measurement wizard 300 is shown in Figure 3, such configuration is provided for illustrative purposes only. Embodiments of the present disclosure may be configured to provide a series of instructions for completing the calibration process.

[0028] FIG. 4 illustrates a method for calibrating an optical diagnostic system using a calibration tool, according to one or more embodiments of the present disclosure. The optical diagnostic system or the calibration tool, or both, used in the method may be as described in FIGS. 1-3. It should be noted that not all steps illustrated in FIG. 4 are required to practice the method. One or more steps may be omitted from or added to the method illustrated in FIG. 4 and the method may still be practiced within the scope of this embodiment. Furthermore, some steps may be performed in a different order and the method may still be practiced within the scope of this embodiment. For example, the method may be configured to begin by first using the optical diagnostic system to scan a machine-readable label placed on at least one pupil of the calibration tool (404). The optical diagnostic system is then aligned and registered with the calibration tool (402).

[0029] The method shown in FIG. 4 generally includes aligning and registering an optical diagnostic system with a calibration tool. The method also includes scanning a machine-readable label disposed on at least one pupil of the calibration tool using the optical diagnostic system. The method further includes storing a set value obtained from the machine-readable label in a storage medium of the optical diagnostic system. The method includes measuring an actual value of the pupil at the calibration tool. The method further includes comparing the actual value to the set value. The method further includes determining that the actual value is within an acceptable range of values.

[0030] As shown in step 402 of FIG. 4, the method includes aligning and positioning the optical diagnostic system with the calibration tool. The alignment and positioning of the optical diagnostic system with the calibration tool may be performed by a user. The position of the calibration tool 100 is aligned with the optical diagnostic system 200 so that the optical diagnostic system 200 may scan at least one pupil 102. Before starting the calibration, the pupil on the calibration tool may be cleaned and checked for visible damage. In addition, the calibration is best performed in a state where there are no external reflections on the pupil of the calibration tool, such as in a darkened ambient light state.

[0031] As shown in step 404 of FIG. 4, the method includes scanning a machine-readable label disposed on at least one pupil of the calibration tool using the optical diagnostic system. The scanning of the machine-readable label disposed on at least one pupil of the calibration tool may be performed by a camera in the optical diagnostic system. The machine-readable label of the calibration tool may include information for performing a calibration for the optical diagnostic system. For example, the information included in the machine-readable label may include an axial length of at least one pupil, a diameter of at least one pupil, a radius of curvature of the eye, and a refractive error. A control measurement wizard may be utilized to prompt the user to scan the machine-readable label disposed on the pupil to initiate a calibration process for the optical diagnostic system.

[0032] 4, the method further includes storing the configuration values ​​obtained from the machine-readable label in a storage medium of the optical diagnostic system. The configuration values ​​obtained from the machine-readable label may be written to an initial / log file portion of the storage medium.

[0033] 4, the method includes measuring actual values ​​of the pupil in the calibration tool. The actual values ​​may include measurements of the axial length of the eye in the calibration tool, the radius of curvature of the cornea of ​​the eye, the refractive error of the eye, and the pupil diameter.

[0034] As shown in step 410 of FIG. 4, the method includes comparing the actual value with the set value. The set value scanned from the machine-readable label and stored in the initial / file log portion of the storage device may be compared to the actual value measured by the optical diagnostic system. For example, the axial length of the eye measured in the calibration tool may be compared to the length of the rod lens stored in the machine-readable label. In another example, the measured radius of curvature of the cornea on the eye may be compared to the radius of curvature of the eye stored in the machine-readable label. In yet another example, the measured refractive error may be compared to the refractive error of the calibration tool stored in the machine-readable label. In another example, the measured pupil diameter may be compared to the pupil diameter stored in the machine-readable label.

[0035] Additionally, as shown in step 412 of FIG. 4, the method includes determining that the actual value is within an acceptable range of set values. The acceptable range may be determined based on requirements set by the optical diagnostic system, requirements set by a calibration tool, requirements set by a manufacturer or user, or requirements set by optical field regulations. If the actual value is within the acceptable range of set values, the calibration process is complete and the optical diagnostic system is now properly calibrated. If the actual value is outside the acceptable range of values, the control measurement wizard may prompt the user to repeat steps 408-412 of the method to recalibrate the system.
