我们报告了在 730 至 870 nm 波长范围的飞秒脉冲照明下测量恶性人类前列腺组织中增生性实质和间质的二次谐波信号。特别是，测量了二次谐波产生与激发波长的关系。这两个区域的结果表现得相当不同，因此为识别组织成分和恶性肿瘤提供了可能的指标。
We report on the measurement of second-harmonic signals from hyperplastic parenchyma and stroma in malignant human prostate tissue under femtosecond pulsed illumination in the wavelength range from 730 to 870 nm. In particular, the relationship of the second-harmonic generation to the excitation wavelength is measured. The result in these two regions behaves considerably differently and thus provides a possible indicator for identifying tissue components and malignancy.
