Abstract

We developed a 2-D imaging system to detect ultra weak biophoton by using a high sensitive fast CCD camera. We installed an illumination apparatus to generate delayed luminescence from plant leaves. Shutters at the illumination system and detector were synchronized to each other. The lens system of the CCD camera was newly designed to accommodate the specific requirements to enhance the collection efficiency for biophoton. Based on the lens simulation, commercial lenses were chose for the lens system. All the equipment was installed in a multi-purpose dark box and the delayed luminescence of Euonymus japonica was successfully acquired.

초 미약 생물광자의 이차원적 영상을 얻기 위해 고속 초고감도 CCD 사진기를 검출기로 사용한 실험 장치를 고안하였다. 본 장치에는 식물의 잎으로부터 방출하는 지연광 (delayed luminescence)를 발생시키기 위한 조명 장치를 설치하였으며, 조명 장치와 검출기에 있는 셔터들은 서로 연동되어 동작하도록 이루어졌다. CCD 사진기에 사용된 렌즈계는, 상용렌즈들로만 구성되었는데, 시료에서 나오는 생물광자의 집광 효율 (collection efficiency)을 높이도록 최적화된 렌즈 설계에서 나온 결과를 기초로 하였다. 이 장치들을 다용도 암 상자에 장착하여 사철나무 잎에서 나오는 지연광의 영상을 성공적으로 얻었다.
