Abstract
The invention discloses a buckling and deforming optical fiber. A thin film is coated on the surface of the optical fiber to form a composite structure that a thin film is coated on an inner core of the optical fiber. The thin film is made of electrostriction materials or piezoelectric materials. An external power supply applies electric field action to the thin film through a fine wire with a coated insulating layer, and the thin film flexibly deforms along the extension direction of the length of the optical fiber to enable the optical fiber to buckle and deform. The buckling and deforming optical fiber is applied to an endoscopic catheter which is composed of the optical fiber. A control system controls the external power supply to control deformation states of the optical fiber, so that the optical fiber can automatically change directions according to control of a doctor to reach a target medical testing position. The buckling and deforming optical fiber is controllable in deformation and can be used in space imaging; when the buckling and deforming optical fiber is applied to the endoscopic catheter, catheter diameter of an endoscope can be decreased and pain of a patient can be relieved.
