近年来，质量评价和控制在生物和农业领域变得越来越重要。对食品植物质量的评价采用了多种检验方法。到目前为止，利用红外区的光声光谱对农作物的谷物进行评估的方法只对玉米进行。我们开发了一种将光声显微镜(PAM)应用于花粉分析的方法。在这项研究中，首次使用PAM来评估作物谷物的质量，在这种情况下，大米。由于对激光的吸收不同，测量了稻米颗粒的均匀性，并将其显示为热图像。分辨率足够好，足以评估一粒大米。这种方法的优点在于它可以用来测量表面和背面有色区域的存在。除了传统的视频图像评估或宏观光学吸收方法外，PA成像还可以评估大米的质量和状况。
Recently, quality evaluation and control has become increasingly important in biology and agriculture. The evaluation of the quality of food plants has been performed by many inspection methods. To date, the evaluation of the grain of crops by photoacoustic spectroscopy in the infrared region has only been performed for corn. We have developed a method of applying a photoacoustic microscope (PAM) to pollen analysis. In this study, a PAM was used to evaluate the quality of crop grains, rice in this case, for the first time. Due to differences in the absorption of the laser beam, the homogeneity of rice grains was measured and shown as thermal images. The resolution was sufficiently good to evaluate a single grain of rice. This method has an advantage in that it can be used to measure the existence of both the surface and back surface colored regions. In addition to conventional video image evaluation or the macroscopic optical absorption method, PA imaging can enable the evaluation of the quality and condition of rice grains.
