ホログラフィック振動画像より干渉縞の抽出に関する一考察 : 情報ディスプレイ,視聴覚技術,画像通信システム,画像応用

Holographic pattern measuring system is a combined system of a holography and a graphic image processing technique. A distribution of microscopical displacement can be measured, and it can be analyzed as the three-dimensional graphic image. However, in the system, the interferometry data have been treated handly, so both the error and the time loss were inevitable. In this Study, the digital image signal processing system was developed, and the system was applied to detect fringes automatically from interferometry image. AS the results, more accurate pattern data could be clearly and speedily detected by using peek-detected processing method.
