Interferometers and autocorrelator based sensors are disclosed that are configured to have multiple sample arms which can be scanned and the backscattered low coherence source light from a sample resolved in a single sweep of one or more variable delays of the sensor. Borescopes and catheters capable of scanning multiple sections or areas of materials and tissues using these sensors are described.

Two stereo images are created by splitting a single image into two images using a field of view dividing splitter. The two images can be displayed side by side so that they can be viewed directly using stereopticon technology, heads-up display, or other 3-D display technology, or they can be separated for individual eye viewing. The two images focus on one imager such that the right image appears on the right side of the monitor and the left image appears on the left side of the monitor. The view of the images is aimed to converge at a given object distance such that the views overlap 100% at the object distance. Measurement is done with at least one onscreen cursor.

The present invention relates to a system and a method for monitoring/tracking the movement of an object in a location which is difficult to access, such as the movement of a patient in a clinical MRI scanner. This is achieved by an optical motion tracking system for determining the movement of an object at least partly located in a volume of difficult access and/or at least partly located in an electromagnetic field, said system comprising a borescope for imaging a pattern on the object or a surface part of the object with a camera, said pattern or surface part located adjacent to a distal end of the borescope and said camera attached to a proximal end of said borescope, and image processing means for calculating the movement of said pattern or surface part relative to the distal end of the borescope based on a plurality of frames/images captured by the camera. The invention further relates to the use of a borescope for motion tracking of an object and a marker plate suitable for use in the motion tracking system.

A borescope device having an insertion tube, a camera head assembly, and a fluid supply system. The camera assembly includes through holes allowing fluid escape. The fluid supply system is controllable to force fluid through the through holes. The fluid supply system may be actuated to cool the camera head assembly.

The present invention provides an apparatus for repairing turbine blades of a gas turbine engine by a laser welding operation. The method uses a miniaturized laser and related apparatus. The miniaturized laser is fed through a borescope access hole to a desired location such as a high pressure turbine blade. The laser is then powered and manipulated so as to perform the desired welding operation. Filler material may also be provided in situ to accomplish the welding procedure. The method realizes a significant cost savings to the vehicle operator in that repairs can be accomplished without the need to remove the engine or disassemble the engine.

A borescope assembly is suitable for detecting a condition of a rotating part. The assembly includes a borescope disposed in a borescope housing and including structure that relays an image to an image viewer. A plurality of fiber optic lines are disposed in the borescope housing, and a strobe light source is coupled with the fiber optic lines. An image processor is coupled with the image viewer. With this structure, the condition of a rotating part can be detected without stopping the part.

Various embodiments include approaches for monitoring turbomachine components. In various particular embodiments, a system for monitoring a component within a turbomachine includes: a borescope probe sized to pass through an opening in the turbomachine, the borescope probe for detecting a symbolic data array on the component within the turbomachine; and at least one computing device operably coupled to the borescope probe, the at least one computing device configured to: obtain image data about the symbolic data array from the borescope probe; evaluate the image data to determine whether the image data is compatible with a symbolic data array analysis program; and analyze the image data using the symbolic data array analysis program in response to determining the image data is compatible with the symbolic data array analysis program.

An apparatus for storing at least one elongated and flexible object, such as an insertion tube that functions as a portion of an endoscope or a borescope device. The apparatus includes a rotating storage carousel having a base and a peripheral barrier. An elongated and flexible object, such as an insertion tube, is stored along the inner side of the peripheral barrier and the base. The storage cavity of the carousel rotates while accepting the transfer of the elongated and flexible object for storage.

Visual inspection of an interior surface of a borehole. A housing adapted to be lowered in the borehole supports a portable camera for generating images of a portion of the interior surface of the borehole and a light source for illuminating an area adjacent the camera. A monitor receives signals from the camera and, in response thereto, displays the images generated by the camera. A viewing envelope positioned adjacent the camera defines a viewing area adjacent the camera, particularly for use in visually inspecting slurry-filled boreholes.

A coolable borescope boss includes cooling passages extending through the boss and oriented for spraying cooling air into a hole extending through the boss. Centerlines of the cooling passages may intersect the a hole axis of the hole. The cooling passages may be cylindrical or open slots disposed through the boss. The boss may be on an arcuate gas turbine engine shroud segment circumscribed about an axial centerline axis. The segment may be part of an annular segmented turbine shroud having cylindrical shroud first and second sections and a conical shroud midsection therebetween and the segment having cylindrical segment first and second sections and a conical segment midsection therebetween. A hole exit of the hole being flush with the conical segment midsection. A borescope plug tip having a spherical tip chamfer may be used to seal against a conical boss chamfer of the boss.

A system and method for performing automated defect detection of blades within an engine is disclosed. The system and method may include an image capture device capable of capturing and transmitting images of a plurality of blades of an engine, creating a normal blade model of an undamaged one of the plurality of blades and determining defects within the plurality of blades by utilizing the normal blade model.

Medical devices, systems, and methods provide improved control over the flexing of an articulated catheter adjacent a therapeutic or diagnostic tool by laterally bending the catheter so as to anchor an articulated portion of the catheter locally relative to an internal tissue site. Alternative embodiments may be used for a wide variety of non-medical applications, including with borescope systems and for other industrial applications.

A computer program product and method for performing automated defect detection of blades within an engine is disclosed. The method may include providing a storage medium for storing data and programs used in processing video images, providing a processing unit for processing images, receiving from a borescope an initial set of images of a plurality of members inside of a device, and using the processing unit to apply Robust Principal Component Analysis to decompose the initial set of images into a first series of low rank component images and a second series of sparse component images, wherein there are at least two images in the initial series.
