Hello everyone I need to ask in a Hand Held Fiber Optic Microscope what should I see when the fiber is considered burnt or distorted ??

This is a bit of an open question but, if one fibre were damaged, I'd expect you to get a missing pixel on the final image. Damage to a fibre will tend to result in light loss through the surface of the damaged section.

Thank you for the reply but like what exactly would I see would is see scratches or like a black spot or what exactly?

Fiber optics

I can't say "exactly" because you haven't said what the exact damage is. All I can say is that your fibre optic must be a coherent array - i.e. the position of each fibre must be the same, relative to the others, at the start and the end of the bunch, transferring the image, pixel by pixel. So the pattern of damage to the fibres will turn up as an equivalent pattern of missing pixels on the final image. Each damaged fibre would probably give a dark pixel and should not interfere with the others. It is unlikely that the image would be distorted unless the sensing end of the array is damaged in some way.

Okay I didn't be clear using Hand Held Fiber Optic Microscope what would you see normally if the fibre works just fine?

How can I tell, if you don't describe the damage?

Usually the damage is when high power is used causing burnt or scratch on the fiber that is what I know if not I would like to know what happens

You will have to be more specific. If you have a problem with language then a diagram may help.

My question is what do you see inside the fiber when using a Hand Held Fiber Optic Microscope if the fiber is not damaged corrupted ? That is the question

Which answer do you want? These are two different questions.

You should contact the vendor; or check with their documentation.

It's impossible to guess without (a) knowing the design, and (b) knowing what kinds of abuse the were applied to the system.
