提出了一种通过优化激发-发射带通滤波器光学降低激发-发射矩阵维数的新方法，并将其应用于猪肉活菌的可视化。理论上使用EEM数据集设计滤波器，用于评估猪肉样品上的菌落形成单位，假设信噪比为100、316或1000。使用新测量的EEM图像对这些滤波器进行评估。设计为S/N = 100时的滤池效果最好，可以可视化活菌分布。该方法有望成为脑电成像应用领域的一个突破。(C) 2013年美国光学学会
A novel method of optically reducing the dimensionality of an excitation-emission matrix (EEM) by optimizing the excitation and emission band-pass filters was proposed and applied to the visualization of viable bacteria on pork. Filters were designed theoretically using an EEM data set for evaluating colony-forming units on pork samples assuming signal-to-noise ratios of 100, 316, or 1000. These filters were evaluated using newly measured EEM images. The filters designed for S/N = 100 performed the best and allowed the visualization of viable bacteria distributions. The proposed method is expected to be a breakthrough in the application of EEM imaging. (C) 2013 Optical Society of America
