PROBLEM TO BE SOLVED: To increase driving speed by improving the optical structure of an optical device without spoiling the light intensity of the optical device. SOLUTION: The optical device is so composed that an input fiber 11 and an output fiber 21, and an input fiber 12 and an output fiber 22, respectively fixed by dual core ferrules 3, are set opposing to each other interposing a movable mirror 6, and one-way condenser lenses 51 and 52 are added. A stroke is made small and the speed is increased by narrowing down only the stroke direction of the movable mirror. COPYRIGHT: (C)2007,JPO&INPIT |
