Shinya Inoue (2011) CIL:11944, Chaetopterus pergamentaceus, oocyte. CIL. Dataset

The movie shows several sequences showing changes in birefringence in oocytes of the marine annelid Chaetopteris that had formed meiotic spindles before exposure to centrifugal force in the Centrifuge Polarizing Microscope developed by S. Inoue. Spindles appear dark or bright according to their directionality with respect to that of the polarized light.

该影片展示了多种序列，描绘了海洋环节动物 Chaetopteris 的卵母细胞在离心力作用下形成减数分裂纺锤体之前的双折射变化。这些纺锤体根据其相对于偏振光方向的不同，呈现出暗或亮的现象。
