Abstract

A display apparatus for optical fiber inspection includes a processor programmed to receive, from a camera, a visual image of an array of endfaces of fiber optic cables being inspected, and to produce, on a display, an inspection interface that includes a first section and a second section. The first section shows a portion of the received image that includes a portion of the endfaces captured in the image. The second section shows a graphical map containing icons that depict representations of the endfaces in the array of endfaces. A selection window identifies the icons representing the endfaces that are currently shown in the first section. In response to user input, the display apparatus correspondingly modifies which endfaces are shown in the first section and modifies the position and/or size of the selection window in the second section.

First claim

The invention claimed is:

1. A display apparatus for optical fiber inspection, comprising:
a display; and
a processor in communication with the display,
wherein the processor is programmed to:
receive, from a camera, a visual image of an array of endfaces of fiber optic cables being inspected, and produce, on the display, an inspection interface that includes:
a first section that shows a portion of the image that includes a portion of the endfaces captured in the image but not all of the endfaces captured in the image; and
a second section that shows:
a graphical map depicting representations of the endfaces in the array, wherein the graphical map includes icons that individually represent each of the endfaces captured in the image; and
a selection window positioned with respect to the graphical map to identify the icons in the graphical map that represent the endfaces that are currently shown in the first section; and

receive user input that correspondingly modifies which endfaces are shown in the first section and modifies the position of the selection window in the second section such that the endfaces shown in the first section are consistently identified in the second section by the icons in the selection window.

2. The display apparatus of claim 1 , wherein at least a portion of the display is a touchscreen and the user input is a swipe gesture detected by the touchscreen, and wherein in response to receiving data from the touchscreen indicating the swipe gesture, the processor is programmed to:
modify the first section of the inspection interface to include a different portion of the image that includes a different portion of the endfaces captured in the image; and
modify the position of the selection window with respect to the graphical map in the second section of the inspection interface such that the selection window consistently identifies the icons in the graphical map that represent the endfaces that are currently shown in the first section of the inspection interface.

3. The display apparatus of claim 2 , wherein the touchscreen detects a swipe gesture indicating motion toward a right side of the touchscreen, and in response, the processor causes:
the first section of the inspection interface to show a portion of the image that is shifted toward a right side of the image; and
the second section of the inspection interface to show the selection window repositioned toward a right side of the graphical map.

4. The display apparatus of claim 2 , wherein the touchscreen detects a swipe gesture indicating motion toward a left side of the touchscreen, and in response, the processor causes:
the first section of the inspection interface to show a portion of the image that is shifted toward a left side of the image; and
the second section of the inspection interface to show the selection window repositioned toward a left side of the graphical map.

5. The display apparatus of claim 2 , wherein the touchscreen comprises at least a portion of the first section of the inspection interface.

6. The display apparatus of claim 5 , wherein the touchscreen is configured to detect a tap gesture indicating a user touch of a particular endface shown in the first section of the inspection interface, and in response, the processor is programmed to modify the first section of the inspection interface to show a portion of the image in which the particular endface is shown enlarged.

7. The display apparatus of claim 6 , wherein the touchscreen is configured to detect a further tap gesture indicating an additional user touch of the touchscreen, and in response, the processor is programmed to modify the first section of the inspection interface to show a portion of the image in which the particular endface is shown further enlarged or reduced in size.

8. The display apparatus of claim 2 , wherein the touchscreen comprises at least a portion of the second section of the inspection interface.

9. The display apparatus of claim 8 , wherein the touchscreen is configured to detect a tap gesture indicating a user touch of a particular icon depicted in the second section of the inspection interface, and in response, the processor is programmed to modify the first section of the inspection interface to show a portion of the image in which the endface represented by the particular icon is shown enlarged.

10. The display apparatus of claim 9 , wherein the touchscreen is configured to detect a further tap gesture indicating an additional user touch of the touchscreen, and in response, the processor is programmed to modify the first section of the inspection interface to show a portion of the image in which the endface represented by the particular icon is shown further enlarged or reduced in size.

11. The display apparatus of claim 1 , wherein the user input is received from an input interface located separate from the display.

12. The display apparatus of claim 1 , wherein the selection window in the second section includes a bordered perimeter and the icons representing the endfaces shown in the first section are depicted within the bordered perimeter of the selection window.

13. The display apparatus of claim 1 , wherein the graphical map in the second section of the inspection interface depicts icons representing all of the endfaces captured in the image.

14. The display apparatus of claim 1 , wherein processor receives video images and derives the image of the array of endfaces from the video images, and wherein the processor automatically updates the portion of the image shown in the first section of the inspection interface based on the video images.

15. The display apparatus of claim 1 , wherein the display apparatus is integrated into an optical fiber inspection apparatus that includes a camera, and wherein the camera is arranged to capture the image of the array of endfaces and communicate the image to the processor.

16. The display apparatus of claim 15 , wherein the camera includes a connection port configured to receive multiple different types of connectors having coupled thereto the fiber optic cables being inspected, each type of connector having the endfaces of the fiber optic cables being inspected arranged in different arrays,
wherein display apparatus is configured to detect the type of connector received by the connection port and identify the array of endfaces presented by the connector, and
wherein the processor is programmed to automatically generate the graphical map in the second section of the inspection interface based on the array of endfaces identified by the detection of the type of the connector.

17. The display apparatus of claim 1 , wherein at least a portion of the display is a touchscreen and the user input is a zoom in gesture detected by the touchscreen, and wherein in response to receiving data from the touchscreen indicating the zoom in gesture, the processor is programmed to:
modify the first section of the inspection interface to include a different portion of the image that includes at least one of the endfaces captured in the image shown enlarged in size based on the zoom in gesture; and
modify a size of the selection window in the second section of the inspection interface such that the selection window consistently identifies at least one icon in the graphical map that represents the at least one endface currently shown in the first section of the inspection interface.

18. The display apparatus of claim 1 , wherein at least a portion of the display is a touchscreen and the user input is a zoom out gesture detected by t
