Title: Measuring method and device for alpha deviation of optical fiber
Inventor: TATSUTA MITSUHIRO
IPC: G01M11/02
Filed: 1980-03-28
Abstract: PURPOSE:To obtain the alpha deviation with high precision, by measuring the frequency characteristic of the optical fiber to detect periodicity of this frequency characteristic. CONSTITUTION:First, the frequency characteristic of the optical fiber is measured by frequency characteristic measuring system 1, and the measured frequency characteristic is displayed or recorded on display part 2. Next, the periodicity peculair to alpha deviation is detected by periodicity detecting part 3. Data of the periodicity detected by detecting part 3 is supplied to data processing part 4, and alpha deviation is calculated there. Since the alpha deviation is inversely proportional to period DELTAf and fiber length L on the basis of the relation of expression 1, a slight alpha deviation such as + or -0.05 is obtained easily if fiber length L is selected properly. In expression 1, N, DELTA, (c), and (alpha-alpha-opt) are the group refractive index, the maximum specific refractive index difference, the light velocity, and the alpha deviation, respectively.

Title: Optical deflector
Inventor: SATO KAZUO
IPC: G02B26/10
Filed: 1986-02-26
Abstract: PURPOSE:To speed up response and to reduce driving electric power by forming a mirror surface substrate and a support part in one structure, providing elastic hinge parts between the both, and using piezoelectric elements as a driving means for the rotary motion of a mirror surface. CONSTITUTION:Metallic electrodes 71 and 72, and 73 and 74 are provided on the top and reverse surfaces of the piezoelectric elements 4 and 4' and connected to different voltage sources 6 and 6' to extend and contract. The mirror surface 1 is put in rotary motion as a result of the up/down parallel movement of support parts 2 and 2' caused by the extension and contraction of the piezoelectric elements, but the elastic hinge parts 3 and 3' absorb being deformation as shown by (b), so the mirror surface 1 is never strained. When the mirror surface is rotated from a state (a) to the state (b), the length of the piezoelectric element 4 is only extended by delta while the length of the other element 4' is shortened by delta, so that the mirror surface 1 is rotated by an angle theta without moving up nor down. In this case, theta(rad)=3delta/l, where lambda is the distance between the hinges 3 and 3'.
