本地，湿鼠尾腱的光学二次谐波产生的角度依赖性显示了一个尖锐的，强烈的，向前的峰叠加在一个广泛的背景。尖锐的峰意味着长程极性顺序，而宽背景对应于用EM观察到的胶原纤维的随机向上/向下阵列的预测。的极性顺序的程度进行了测定，并测定的年龄和水合状态的原纤维直径分布的依赖性。的相干长度的肌腱谐波产生和胶原纤维的非线性磁化率的绝对大小进行了测定。这些发现的生物学意义进行了讨论。
The angular dependence of optical 2nd-harmonic generation by native, wet rat tail tendon displayed a sharp, intense, forward peak superimposed on a broad background. The sharp peak implied long-range polar order while the broad background corresponded to that predicted for the random up/down array of collagen fibrils seen with the EM. The degree of polar order was determined, and the dependence of the fibril diameter distribution on age and state of hydration was measured. The coherence length of tendon for harmonic generation and the absolute magnitude of the nonlinear susceptibility of the collagen fibril were determined. The biological significance of these findings is discussed.
