FIBERSCOPE, AN APPLICATION OF FIBER OPTICS
Optical fiber possesses the greatest advantage of being flexible. It is a transparent fiber made by drawing glass, silica or plastic to a diameter which is as thick as a human hair making it one of the best things since sliced bread. Optical fibers are widely used to transmit light between the two extreme ends of the fiber. They are accepted in fiber-optic communications, where they allow transmission over longer distances with higher bandwidths as compared to electric cables. Some of the best-known applications of fiber optics are fiberscope, fiber optic sensors, and fiber lasers.
A Fiberscope is a flexible instrument that is constructed by bundling optical fiber with an eyepiece on one end and lens attached to the other side. The human eye can recognize something as impossible as emotions, but it fails to reach places of the micro level. It is used to conduct examination and inspection of tiny things and places which are difficult to reach such as interiors of the machine, the human body, and locks. It is inserted into the item that needs to be explored without destroying or disassembling the item under observation.
COMPONENTS OF FIBERSCOPE
- EYEPIECE: This section of the instrument magnifies the image which is carried back through the imaging bundle. As a result, the human eye can view it.
- IMAGING BUNDLE: This is the major part of fiber optics which consists of flexible glass fibers that help in transmitting the image to the eyepiece.
- DISTAL LENS: It is another major section and is connected to the other end of the optical cables. It is the combination of microlenses that accepts images and focuses them into a small imaging bundle.
- ARTICULATION SYSTEM: It is defined as the ability of the user to control the movement of the section that performs bending in the fiberscope. It is directly attached to the distal lens.
- INSERTION TUBE: It constitutes to most of the part of the fiberscope and is made up of durable and flexible material. It protects the optical fiber bundle and the articulation cables.
- BENDING SECTION: It is the most flexible part of the instrument and connects the insertion tube with the distal viewing section.
- DISTAL SECTION: A fiberscope is a blend of illumination bundles and imaging fiber bundles. The point where they intersect is the distal section.
The applications of Fiberscope in the medical field is of great significance. It is used by doctors and surgeons to examine problems in a patient’s body without going through the tedious and painful procedure of large incisions. This process is known as endoscopy. This method is used to diagnose a patient’s infected, and damaged organs. Like Fiberscope, Sewer Camera is also a type of micro instrument which helps to detect problems in sewage pipes.
