Proposal of compact optical system using planar lightwave circuit for precision measurement based on levitation mass method Koichi Maru1,a and Yusaku Fujii1,b 1Department of Electronic Engineering, Gunma University, Kiryu Gunma 376-8515, Japan amaru@el.gunma-u.ac.jp, bfujii@el.gunma-u.ac.jp Keywords: Planar lightwave circuit; Levitation Mass Method; precision measurement Abstract.
On the other hand, Fujii et al. have proposed a method based on the law of conservation of momentum, in which an impulse is generated and directly transferred to the transducer being tested [2,3].

In order to determine yield point (YP), ultimate tensile strength (UTS) and total elongation (El) tensile test experiments were performed.
