Flexible fiber optic endoscopes for visual inspection of objects with complex geometry and objects that cannot be directly accessed. Examples of such objects can be gas turbines, electric motors, turbogenerators, boilers, heat exchangers, water pipes, sewers, industrial communications. To facilitate the introduction of the working part of the endoscope into the examined space, it is made flexible. The ability to control the bending of the head part greatly simplifies the passage of the examined cavities.
