O
ptoelectronic devices are the foundation of optical fiber communication system and optical fiber sensor system. With the
development of optical fiber communication, alignment and between planar optical waveguide chip (POW chip) and optical
fiber array (OFA) have become the focus of many industries. In general, the alignment is performed passively and actively. During
passive alignment, the two optical components may be placed according the expected desired orientation. Machine vision can be
used in passive alignment to locate the position of the two optical components, then used to guide the movement of the motor stage
for the alignment. Optical component edge detection is one of the key steps of machine vision in alignment. This paper has proposed
a line detection algorithm based on the progressive probabilistic Hough transform (PPHT) and iteratively reweighted least squares
(IRLS) algorithm for alignment between planar optical waveguide chip and optical fiber array. The experiment results show that the
detection angle error is less than 0.005º and the time consumption is less than 0.5 s through the proposed algorithm. Besides, it also
can accurately fit optical component edge with some non-random factors. Therefore, the proposed new algorithm has the advantages
of high precision, fast computing speed and good robustness and it can successfully realize the high-precision fast line detection of
optical component edge.
