摘要
We adapt the improved scanning focused refractive-index microscopy (SFRIM) technique to the quantitative study of biological tissues. Delicate refractive index (RI) imaging of a porcine muscle tissue is obtained in a reflection mode. Some modifications are made to the SFRIM for better two dimension (2-D) observation of the tissues. The RI accuracy is 0.002. The central spatial resolution of SFRIM achieves 1 mu m, smaller than the size of the focal spot. Our method is free from signal distortion. The experimental result demonstrates that SFRIM is a potential technique in a wide field of biomedical research.
