TECHNICAL FIELD
The present disclosure relates to inspection scopes and, in particular, to inspection scopes adapted for use with mobile electronic devices.
BACKGROUND
Mobile electronic devices, for example smartphones, are commonly used for image and video capture. However, mobile electronic devices may be too bulky to capture images and video in small or confined spaces. Further, a user may be precluded from capturing images or video in a location not reachable by the device user's hand, arm, or person. Accordingly, a device for enabling image and video capture by a mobile electronic device in small or remote spaces is desirable.
SUMMARY
In an exemplary embodiment, an inspection scope for a mobile electronic device comprises a lens component configured to acquire an image, an image guide component configured to transmit the image to an image capture component of a mobile device, and a mounting component configured to releasably couple the inspection scope to the mobile device.
In another exemplary embodiment, an inspection scope for a mobile electronic device comprises a camera component configured to acquire an image, an image cable configured to transmit the image acquired by the camera component to the mobile device, and a flexible tubing that at least partially surrounds the camera component and the image cable.
In another exemplary embodiment, a method of using an inspection scope for a mobile electronic device comprises coupling the inspection scope to the mobile electronic device, and opening an inspection scope application on a mobile device. The method further comprises focusing, via the inspection scope application, an image of a target area, and instructing, via the inspection scope application, the mobile electronic device to capture an image of the target area via a camera of the mobile electronic device.
The contents of this summary section are presented as a simplified introduction to the disclosure, and are not intended to be used to limit the scope of any claim.

Inspection scope 100 is configured to couple to a mobile electronic device so that the mobile electronic device can display and/or record the images or video. Inspection scope 100 is portable and flexible, and is configured to illuminate a target area for viewing. In various exemplary embodiments, inspection scope 100 may comprise a flexible tubing 131 that is positionable and has a sufficient length (for example, 18 inches, 24 inches, 36 inches, 48 inches, and/or the like) to allow a user to bend and/or position inspection scope 100 or a portion thereof, as desired. In various exemplary embodiments, flexible tubing 131 may be at least partially bifurcated, and the bifurcated portion may comprise an image guide tube 134 and an illumination tube 133.
In certain exemplary embodiments, lens component 110 is disposed at a capture end 111 of inspection scope 100.

Optical fibers for illumination 125 may be configured for transmitting light from a mobile electronic device or component thereof (for example, from a flash LED associated with a camera of the mobile electronic device) to the capture end 111 of inspection scope 100 and toward the target area.
In various embodiments and with reference again to FIGS. 3B, 3C, and 3D, optical fibers for illumination 125 and optical fibers for imaging (for example, as comprising image guide component 130) may desirably be separated and/or adjustable with respect to one another in order to interface correctly with a variety of mobile electronic devices and/or in order to improve illumination of the target area. With reference now to FIG. 3B, optical fibers for illumination 125 may be disposed at least partially within an illumination lumen 124, which is disposed at least partially within flexible tubing 131. The illumination lumen 124 may be configured to segregate optical fibers for illumination 125 from other components of inspection scope 100 disposed at least partially within flexible tubing 131. That being said, in accordance with various embodiments and with reference to FIG. 3A, optical fibers for illumination 125 may be unsegregated from other components disposed within flexible tubing 131. With reference now to FIGS. 3C and 3D, optical fibers for illumination 125 may be disposed around an outer circumference of image guide component 130. In various exemplary embodiments, optical fibers for illumination 125 may be configured with a diameter of up to about 0.25 mm. That being said, optical fibers for illumination 125 may be configured with any diameter suitable for light transmission to the target area.

In this manner, inspection scope 100 may provide a suitable viewing and/or image capture result across multiple mobile electronic devices and/or in spite of environmental variations such as heat, cold, humidity, and/or the like.
In some embodiments, inspection scope 100 may be constructed with nonconductive materials. In this manner, inspection scope 100 may be suitable for use in electrically risky or otherwise hazardous areas. Additionally, inspection scope 100 may be configured with an image splitter in order to deliver images to multiple destinations simultaneously, for example to an eye and to a mobile electronic device.
In certain exemplary embodiments and with reference again to FIG. 2, inspection scope 100 may be configured with a focus block or focus guide. The focus block may be placed, for example, in the same focal plane as the termination of image guide component 130 at the capture end 111. The focus block may also be embedded in the termination of image guide component 130 at the capture end 111. In this manner, a mobile electronic device coupled to inspection scope 100 may more accurately focus or auto-focus on the termination of image guide component 130 in order to obtain an image of sufficient clarity and sharpness.
With reference now to FIGS. 6-8, in various exemplary embodiments, an inspection scope 100 may be configured to be electrically coupleable to other devices, for example a smartphone, tablet, or similar mobile electronic device.
