Title: Akira Aikawa: Innovator in Optical Fiber Technology
Introduction
Akira Aikawa is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical fiber technology, holding a total of 2 patents. His innovative methods for detecting defects in optical fibers have advanced the capabilities of fiber optic systems.
Latest Patents
Aikawa's latest patents focus on methods for detecting defects in optical fibers. The first patent describes a defect detecting method that utilizes a laser beam to illuminate the optical fiber. This method analyzes the intensity distribution pattern obtained from the laser illumination, applying both weak and strong smoothing processes to create first and second patterns. A judging pattern is then formed based on the difference or quotient between these patterns, which is subjected to a Fourier transform for evaluation. The defect is detected by assessing the dispersion of the Fourier transform pattern from a judging curve.
The second patent also addresses defect detection in optical fibers. In this method, a laser beam is illuminated onto the optical fiber from a transverse direction. The intensity distribution of the forward scattering light is analyzed, and similar smoothing processes are applied to form first and second patterns. The defect is detected by evaluating the magnitude of the judging pattern, which is again subjected to a Fourier transform to create a frequency spectrum pattern. The evaluation of this pattern is conducted using a double logarithmic axis, leading to the detection of defects based on the dispersion from a judging curve.
