Title: Method for collating coated optical fiber
Inventor: NAKAMURA HIROSHI
IPC: G01M11/00
Filed: 1989-09-28
Abstract: PURPOSE:To extremely easily identify coated fibers without increasing an insertion loss by bending the part near the light input of a part for detecting the coated fiber to a specific bending radius and collating the coated fiber. CONSTITUTION:The coated optical fiber is collated by so bending the part near the light input of the part 3a for detecting the coated fiber 2 that the bending radius (r) attains 15D<=r<=35D (D denotes the diameter of the coated fiber) at the time of detecting the leak light of the coated fiber to collate the coated fiber by inserting the coated optical fiber into the photodetecting part 3a of a coated fiber collating device. The coated fiber 2 near the light input side of the detecting part is bent at the prescribed radius of bending, by which a clad mode or coating propagation mode is partly generated without imparting the increase of the propagation loss to the coated fiber 2 and, therefore, the quantity of leak light is increased and the collation of the coated fiber is execut ed even for the coated fiber with which the leak light is small.

Abstract: PURPOSE:To reduce an erroneous operation due to ambient light or disturbance light, etc., of a supervisory area by providing an image inputting means, an image processing means, an abnormality judging means, an outputting means, etc. CONSTITUTION:Light projected from a light source array is reflected by the background in a supervisory area, and the reflected light is received by an image inputting means 1, and reflection luminance signals are detected in time series. The output of the means 1 is stored in a present image memory 15 in an image processing means 2 that stores images taken in at every fixed time and a reference image memory 16 that stores the certain state of the supervisory area. Then, luminance data stored in memories 15, 16 are subtracted 17 at every picture element. A binarization circuit 18 binary-codes these picture elements to '1' when the output of the subtracter circuit 17 is changed to above a threshold V0, and to '0' when changed to below the threshold V0. When the present image detected by the means 1 differs from stored 16 state, the output of the circuit 17 changes to above threshold V1, the circuit 18 outputs '1'. When there is at least one picture element that become '1' in output of the means 2, abnormality judging means 3 gives an alarm output to an outputting means 4.
