项目摘要
Purpose of the present research is to develop a highly sensitive measurement system to monitor the various conditions and activities of plant based on optical interferometric techniques using laser speckle, such as electronic speckle pattern interferometry (ESPI), statistical interferometry (SI), speckle difference method. The information concerned with the biological activities such as growth lies in the scattered light field from the surface of the plant. To obtain such information, we have applied SI and ESPI. Aiming to establish an optical method to monitor the influences of environmental conditions and environmental pollution on the plants, experiments were conducted using ozone as a representative substance of air pollution. The SI has achieved extremely high sensitivity to measure the expansion of object. Using SI, the growth speed of the leaves of plants could be successfully measured with the sensitivity of subnano meter scale and with very high temporal resolution of second s … More cale. It was clearly demonstrated that SI could detect the change of the plant growth for the 0.12 ppm ozone exposure, which is the density level to issue a photochemical oxidant warning in Japan. Since there was no method to observe the behavior of plant with such a high temporal resolution at nano menter scale so far, various interesting behaviors of plants were newly revealed through the present research project. One of new discoveries is that the growth speed of the plant is never constant but fluctuating all the time. It was found that the ratio of the standard deviations of fluctuation in growth speed of plant before and after the ozone exposure depends on the ozone density. This quantity may lead to a figure for the air pollution and its influence on the plants.ESPI has applied to observe the blooming process and geotoropism of the plants. The validity of the method to observe the adaptation of plant for the change of environmental conditions was experimentally confirmed.Those optical methods have also applied to observe the growth of plant roots. As experimental results, it was shown that SI is more appropriate for such a thin object as root and because of its high sensitivity. Less
本研究的目的是开发一种基于激光散斑光学干涉技术的高灵敏度测量系统,如电子散斑干涉法(ESPI)、统计干涉法(SI)、散斑差法等。与植物生长等生物学活动有关的信息存在于植物表面的散射光场中。为了获得这样的信息,我们应用了SI和ESPI。为了建立一种光学方法来监测环境条件和环境污染对植物的影响,以臭氧作为空气污染的代表物质进行了实验。对于测量物体的扩展,SI达到了极高的灵敏度。利用SI,可以成功地测量出植物叶片的生长速度,具有亚纳米级的灵敏度和很高的时间分辨率,第二个S…更大的勇气。结果表明,在0.12ppm的臭氧暴露下,SI可以检测到植物生长的变化,这是日本发出光化学氧化剂预警的浓度水平。由于到目前为止还没有在纳米尺度上以如此高的时间分辨率观察植物行为的方法,因此本研究项目新地揭示了植物各种有趣的行为。新的发现之一是,植物的生长速度从来不是恒定的,而是一直在波动。结果表明,臭氧暴露前后植物生长速度波动的标准差之比取决于臭氧浓度。ESPI已应用于观测植物的开花过程和向地性。通过实验验证了该方法在观察植物对环境条件变化的适应性方面的有效性,并将这些光学方法应用于植物根系的生长观察。实验结果表明,SI更适合于像根部这样的薄物体,因为它具有很高的灵敏度。较少
