fibriscopes

A fiberscope is a flexible optical instrument used for viewing inaccessible areas. It consists of a bundle of optical fibers, typically enclosed in a flexible sheath. Each optical fiber transmits light, allowing images to be viewed at the opposite end. The fibers are arranged in a precise pattern to maintain the spatial integrity of the image.

Fiberscopes are commonly used in medical and industrial applications. In medicine, they are employed for minimally invasive diagnostic and surgical procedures, allowing doctors to visualize internal organs and tissues without major surgery. Examples include gastroscopy, bronchoscopy, and laparoscopy. In industry, fiberscopes are used for inspecting the internal components of machinery, engines, and pipelines, detecting defects or damage in hard-to-reach places.

The illumination of the area being viewed is often provided by a separate light source, which can be transmitted through additional fibers within the scope or through an external light guide. The image is viewed through an eyepiece or transmitted to a video monitor. The flexibility of the fiberscope allows it to navigate through curved or narrow passages. The image quality is dependent on the number and quality of the optical fibers in the bundle. Modern fiberscopes often incorporate additional channels for air, water, or the passage of small instruments.
