측면 파노라마 영상 구현을 위한 광섬유 내시경 프로브에 대한 연구

Abstract

In this paper, we introduce optical probes that can acquire side view optical images at one time without using a mechanical scanning device. In the conventional optical image acquisition method, irradiated light beam is rotated by using a mechanical scanning device. However, in this method, not only the image acquisition takes a long time but also the synchronization of operational speed between the mechanical rotation and the image acquisition is not properly performed, thus causing a problem in detecting an accurate optical image. To solve this problem, an optical probe capable of transmitting light to a cylindrical sample and receiving reflected light using a cone-shaped reflecting mirror is proposed. By using the proposed side-view optical imaging probe, I confirmed the potential of the proposed method by acquiring images of the pattern and characters written on the inner surface of the cylindrical sample and the fluorescent image of the surface overlaid with the fluorescent beads.
