赤外線を用いた非侵襲でのニワトリ胚の計測システムの開発

抄録

Our laboratory has attempted to measure chick embryos directly by a CCD camera through the hole opened at blank end of the eggs. Previous studies showed that this hole has not influenced to embryonic development. We aimed to develop the non-invasive image recording system by infrared light as a better measurement system. As a result, a wavelength of the 850nm was better in terms of penetration of the forefinger and the distinguishment of vessels. However, light of 850nm and its peripheral wavelength could not distinctly distinguish both chick and blue-breasted quail embryos. In this research, the developed system could not clearly observe embryos non-invasively. Other wavelengths/light intensions or different techniques (e.g., using a sensitive or a high resolution receiving element for the infrared light) should be tried on this system in the future study.
