Paper Abstract
A new optical fiber sensor with 2 light beams is developped for
detecting variation of scattered light distribution caused by surface
defects, like flaws, surface inferiority, etc. Its feature consists
in compact structure using only light transmission characteristic
proper to the optical fiber, using no optical components like a lens.
High response speed of maximum 2m/s is suited to purpose of non con-
tact in-process or in-line defect detection and with automation of
inspection process performed in the past visual or sampling method,
the stabilization of inspection level is achieved and inspection eff i-
ciency is improved by introduction of this sensor.
In this paper, the principle of surface defect detection with the
optical fiber sensor and the quantification of surface properties by
conversion of detection output into arithmetical mean deviation are
described, and the system structure on representative examples of
practical application in actual inspection process is explained.
