Title:
OPTICAL SWITCH AND SPECTROMETER CONTROLLER USING THE OPTICAL SWITCH
Document Type and Number:
Japanese Patent JPH01136113
Kind Code:
A
Abstract:

PURPOSE: To slightly generate optical attenuation for connection and to reproduce the attenuation by allowing the relative arrangement of connection means to 1st and 2nd elements to permit the connection means of a 1st group related to all pairs of connection means selected from a 2nd group by rotation around a main axial line.

CONSTITUTION: The switch consists of a fixed cylindrical element 2 fitted to a supporting body 4 and an element 6 having the same axial line X as the element 2 and the element 6 can be rotated around the axial line X common to the two elements 2, 6. Although other fibers F3 to F2n+1 are fixed to the fixed element 2, fibers F1, F2 are fixed to the movable element 6 forming a cylinder. Connectors C1, C2 are fixed to the element 6 and connectors C3 to C2n+2 are fixed to the element 2. Consequently signals corresponding to various measuring paths are penetrated into the fibers related by the switch and slight attenuation and the attenuation is reproduced.
