For non-medical use,similar instruments are called borescopes.
Rigid or flexible borescopes may be fitted with an imaging or video device.
Minimal quantity is 10,000 pixels while the best images are obtained with higher numbers of fibers in the 15,000 to 22,000 pixels range for the larger diameter borescopes.
Flexible or rigid borescopes may be equipped with a video or imaging device.
There is a minimum amount of 10,000 pixels required, but the best images are captured with higher numbers in the range of 15,000 and 22,000 for borescopes with larger diameters.
For very small rigid borescopes(under 3mm), the gradient index lens relays are better.
Fiber content in the flexible relay is also critical to provide the highest possible resolution to the viewer.Minimal quantity is 10,000 pixels while the best images are obtained with higher numbers of fibers in the 15,000 to 22,000 range for the larger diameter borescopes.
Borescopes are mostly used in NDT techniques for recognizing defects or imperfections.
Because the complex optical wave guide is replaced with an inexpensive electrical cable,video borescopes can be much less costly and potentially better resolution(depending on the specifications of the camera).
Flexible borescopes suffer from pixelation and pixel crosstalk due to the fiber image guide.
Because a complex fiber optic waveguide in a traditional borescope is replaced with an inexpensive electrical cable,video borescopes can be much less costly and potentially better resolution(depending on the specifications of the camera).
Rigid borescopes have the limitation that access to what is to be viewed must be in a straight line.
In World War II,primitive rigid borescopes were used to examine the interior bores(hence"bore" scope) of large guns for defects.[1].
Rigid borescopes are similar to fiberscopes but generally provide a superior image at lower cost compared to a flexible borescope.
Some high-end borescopes offer a“visual grid” on image captures to assist in evaluating the size of an area with a problem.
For flexible borescopes, articulation mechanism components, range of articulation, field of view and angles of view of the objective lens are also important.
Rigid borescopes are therefore better suited to certain tasks such as inspecting automotive cylinders, fuel injectors and hydraulic manifold bodies, and gunsmithing.
Borescopes are commonly used in the visual inspection of aircraft engines, aeroderivative industrial gas turbines, steam turbines, diesel engines, and automotive and truck engines.
Borescopes are used for visual inspection work where the area to be inspected is inaccessible by other means, or where accessibility may require destructive, time-consuming and/or expensive dismounting activities.
For large diameter borescopes(over 12mm), the achromatic doublet relays work quite well, but as the diameter of the borescope tube gets smaller the Hopkins rod lens and gradient index rod lens designs provide superior images.
