A system for monitoring a process inside a high temperature semiconductor process chamber by capturing images is disclosed. Images are captured through a borescope by a camera. The borescope is protected from high temperatures by a reflective sheath and an Infrared (IR) cut-off filter. Images can be viewed on a monitor and can be recorded by a video recording device. Images can also be processed by a machine vision system. The system can monitor the susceptor and a substrate on the susceptor and surrounding structures. Deviations from preferred geometries of the substrate and deviations from preferred positions of susceptor and the substrate can be detected. Actions based on the detections of deviations can be taken to improve the performance of the process. Illumination of a substrate by a laser for detecting deviations in substrate geometry and position is also disclosed.

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.

A business model algorithm for maintaining aircraft engines in reliable and safe operating condition without the necessity of performing major engine overhaul in which engine manufacturers' maintenance procedures are enhanced and performed more frequently and supplemented by engine trend analysis, engine oil analysis, engine vibration analysis, borescope inspection and computer algorithm forecasting to identify, repair, and / or replace engine components without necessity of major engine overhaul.

A system and method for improving human-machine interface while performing automated defect detection is disclosed. The system and method may include an image capture device for capturing and transmitting data of an object, performing automated analysis of the data and reviewing results of the automated analysis by a human inspector and providing feedback. The system and method may further include refining the automated analysis of the data based upon the feedback of the human inspector.

A borescope is received within a housing. The borescope includes a flexible end portion carrying the video head and a housing includes a flexible end portion comprised of ball-socket segments and a tip for following the movement of the flexible end portion of the borescope. Cooling air is provided in an annular passage between the borescope and housing for flow about the borescope to maintain the video head temperature below its temperature limitation. Two cables maintain the ball-socket segments and tip in contact with a transition piece and with one another to enable the flexible borescope end portion to follow the movement of the directionally controlled video head.

The present invention relates to the analysis of the internal structures of objects using optical means. According to the invention there were designed an apparatus suited for optical coherence tomography (OCT), an optical fiber lateral scanner (15), which is a part of said apparatus and is incorporated into an optical fiber probe (8), and a method for studying biological tissue in vivo, which allows for making a diagnostics of the biological tissue under study on basis of the state of the basal membrane (46). The moving part of lateral scanner (15) of sampling arm (4) of interferometer (2) is arranged comprising a current conductor (19), which envelopes a magnetic system (17) in the area of one of its poles (25) and an optical fiber (13), which is rigidly fastened to current conductor (19), whereas optical fiber (13) serves as a flexible cantilever, allowing to miniaturize the optical fiber probe (8). Constructing magnetic system (17) as two permanent magnets (22, 28) which are aligned at their analogous poles (25, 29), and placing optical fiber (13) in a throughhole (30), the throughhole (30) being formed by the facing grooves made in said analogous poles (25, 29) of permanent magnets (22, 28), ensure optimization of the design of optical fiber probe (8), the body (11) of said optical fiber probe (8) having limited dimensions. Optical fiber probe (8) is placed at the distal end of an instrumental channel of an endoscope or borescope. Studying of biological tissue in vivo with the aid of the developed apparatus allows for non-invasive diagnostics of biological tissue on basis of the state of basal membrane (46).

Measurement accuracy of a remote visual inspection (RVI) system is tested using a test object including a test feature having a known geometric characteristic. Using a controller, attachment of a detachable measurement optical tip to an RVI probe is detected. A user is then prompted to perform testing of the measurement accuracy. When the user indicates the test feature is visible, the system captures one or more images of the test feature, determines coordinates of the test feature from the images, and measures a geometric characteristic of the test feature using the coordinates. An accuracy result is determined using the measured geometric characteristic and the known geometric characteristic, and an indication is provided, e.g., to the user, of the result of the comparison. An RVI system with a user-prompt device is also described.

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.
