| 中文摘要: |
| 使用PIAS（光子计数图象采集系统），记录了大麦品种Igri种子萌发期的超微弱光子辐射现象，对这种混在强噪声中的光子辐射进行处理后获得了清晰的发光图象。研究表明：对生物系统的超微弱光子辐射进行二维成象，可以比时间域一维探测获得更多的生理信息。采用数字图象处理技术，选择合适的阈值亮度，可以把光子辐射和噪声有效地区分开。 |
| 英文摘要: |
| PIAS (Photon Counting Image Acquisition System, Hamamatsu, K. K) wasused to record the phenomena of ultra-weak photon emission in the germination of barleyIgri. Photon Images that is relatively clear were obtained after the photon emission withstrong noise was processed. The result show that much more biological information than onedimensional detection in time domain could be acquired by analysis of the two dimensionalimage of ultra-weak photon emission. The photon emission and the noise could be effectivelyseparated by selecting appropriate threshold level. |
