OPTICAL FIBER PROBE

PURPOSE:To improve the operability by varying the irradiation direction of a laser light without moving a screen which is being observed by providing members bent by a control signal from the outside along a probe in the vicinity of the tip part of the probe so that they go straight to each other. CONSTITUTION:A member 3 bent by a control signal consists of two layers, 3a is a heating element and its temperature is varied by a control signal, and 3b is a member bent in the direction (direction of the reverse side and the surface side of the paper surface) as indicated with an arrow 5 in accordance with a temperature, consists of, for instance, a member of a bimetal structure, and to the heating element 3a, a lead wire 4 is connected. Also, as for the member 3 bent by a control signal, two are provided in orthogonal positions so that orthogonal bending can be executed to each other. When a temperature of the heating element 3a is varied by a control signal transmitted from a control signal generated circuit, the member 3b consisting of a bimetal, etc., is bent to a curvature corresponding to a temperature. The member 3 is formed integrally with a resin tube for constituting the tip part of a laser probe, the tip part of the laser probe is bent to a curvature corresponding to the control signal and the purpose is attained.
