A fiber optic scope has the ability to see around a bend and capture images of hard to reach places.
Any small opening is enough to slide it through and will allow you to see and capture images with clarity, depending on the light conditions of course.
Viewing scopes like these make use of the reflective properties of light.... sort of having a mirror to reflect light around a corner.
Imagine having two or more mirrors reflecting light in this way and you can clearly see why it is possible to project an image, even if the scope is curved.
Covert surveillance operations:
For use by private investigators and law enforcement officers. Slide the viewer scope underneath a door and see what is going on behind closed doors.
During rescue operations in restricted spaces:
Use fiber optic viewing scopes to determine the exact location of the child or animal to ensure safe recovery.
Basically, fiber inspection scopes can be used in any place that is hard to reach and not easily seen with the naked eye... like car engines, small pipes etc.
Fiber optic viewing scopes like these have different lengths and if you want to record the action, you can also use a special camcorder adapter that will connect to your camcorder.
It's is a neat little tool for all those hard to reach spaces.
